Product Description
Steel Metal Prefabricated Buildings with Turnkey Solution

prefabricated building, informally a prefab, is a building that is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on-site to form the complete building. 

Prefabricated buildng has wide applications-residential, industrial, commercial and other purposes. KXD's team could provide you

I. Residential Prefabricated Building: 

A. Single floor residential prefabricated building

Single floor residential prefabricated building could apply for both temporary/contemporary houses whether in prefabricated solution or modular solution. 



B. Multi floor residential prefabricated building

Multi-story residential prefabricated building is able to apply for apartment and condo use. 

The primary structural elements of a multi-storey residential prefabricated building, namely the columns and floor beams, should be laid out with a view to minimising both the cost of the steelwork and the time required for its erection. For any given structure a layout can be determined that optimises the combined beam and column content of the structure, but in most cases functional and architectural considerations have to be taken into account, which mitigates against the design of optimal bay sizes. Consultation between the architect and the engineer in the early stages of planning could help to prevent an uneconomical layout having to be adopted. 

The third structural element, after the columns and beams, is 
the stabilising system necessary to provide lateral support to the building, i. e. To supply stability under gravity loading and to resist the overturning effects of windObviously, the taller the building the more important the bracing system becomes and in very tall structures the provision of adequate lateral support does in fact become the dominant consideration. 

Lateral stability may be provided within the steel structure itself by means of bracing, or moment-resisting beam-column connections or steel shearwalls, or it may be imparted by other building elements, e. G. Reinforced concrete service towers, or concrete or brick in-fill panels in the walls. In all cases the stabilising elements may be located within the plan dimensions of the building or in the perimeter walls, or they may even be external to the building. 

If a building is to incorporate the stabilising system within the steel structure, the framework can be of the 
two-way braced, one-way braced and one-way-rigid, or two-way rigid type. Triangulated bracing is usually cheaper than a stiff moment-resisting frame and should be used wherever access problems do not arise, i. e. Where door, window or service openings are not required. 

In addition to vertical bracing systems it is necessary to provide stiffness within the plane of each floor, both to maintain the squareness of the floor in plan and to transmit the wind loading on the exterior of the building to the vertical bracing. 

Stabilising systems - examples
Figs 7.1 to 7.5 give examples of various bracing systems that can be employed to provide stability to multi-storey buildings. The examples are of general application and illustrate the basic principles involved in such systems. The vertical steel bracing is shown as the X-type for simplicity, but could equally well be chevron bracing, knee bracing or someother type (the features of the various bracing types are discussed more fully in Chapter 11). The floors are shown as steel-braced, but in practice the bracing function could be furnished by the concrete floor slab, in which case only nominal squaring-up
Steel bracing would be required. The systems are applicable to buildings of almost any number of storeys. 

Two-way steel bracing
The two-way steel braced system shown in Fig 7.1 is one of the most efficient in terms of stiffness, speed of erection and economy. All beam-to-column connections are of the simple (i. e. Hinged) type, so labour input in both columns and beams is minimised and erection can proceed quickly. Being fully steel-framed, the structure is self-supporting and can be completely erected without having to be integrated with other trades. The only drawback is the presence of the braced panels in the exterior walls, which might interfere with the window pattern, but in the light of the current trend towards exposed steelwork
The windows could be set back and the bracing system be expressed boldly as an architectural feature. In very long buildings it would be necessary to provide one or more interior sets of bracing, as shown dotted. 

One-way steel bracing
The stiff frame shown in the alternative end elevation of Fig 7.1 is another method of providing transverse stiffness to the structure. All of the transverse frames not only the end ones, would be stiff, but the building would still rely for longitudinal stiffness on the two sets of one-way bracing in the sides. This would be a more costly arrangement than the two-way braced solution, but would remove the drawbacks of the triangulated bracing. 

It is more suited to long buildings and has the further advantage that the main (i. e. Transverse) floor beams could be shallower, because of their continuity, with consequent reduction in storey height. It must be emphasised, however, that on purely economic grounds triangulated bracing is very much more cost-effective than a moment frame, both in shop fabrication and in erection. 

Central service core
Where a building is fairly compact in plan and does not have a great length-to-width ratio, a central service core is a very efficient means of providing stability, as shown in Fig 7.2. E Elevation

Floor framing
In steel-framed buildings the floor framing system almost invariably consists of a series of main and secondary beams at right angles to each other in plan, with the secondary beams framing into or passing over the tops of the main beams. The floor slab or deck is then carried on top of the secondary beams. 

Except where stiff-frame action is required, as discussed under Stabilising Systems above, the main beams are usually simply-supported spans between the columns. If the secondary beams have their top flanges flush with the tops of the main beams they would be framed into the webs of the main beams and would thus also be simply-supported; This would produce a floor grid of minimum depth and would result in a reduction in storey height. However, underfloor services running at right angles to the main beams would then have to pass through holes formed in the webs of these beams, or else be routed
Below the main beams, which would increase the floor depth. 

If the secondary beams pass over the tops of the main beams, however, they would no longer be simply-supported but be continuous, significantly reducing the mass and especially deflection. The routing of services in both rectangular directions in plan would be facilitated by reason of the space available above the main beams. 

The two beam framing systems referred to above represent conventional practice as used on the great majority of small to medium-sized buildings. The beams are ofstraightforward construction and employ standard end connections and are thus easy and cheap to fabricate. A number of non-standard options are available and are worth considering for larger buildings where a high level of repetition of components would justify their use. These are discussed below. 

Twin beams
Main beams span between columns and can therefore not normally be made continuous. Continuity can, however, be achieved by replacing the beam by a pair of closely-spaced twin beams passing on each side of the column, as shown in Fig 7.6. 

Because of their continuity the main beams can now be designed plastically, for acombined moment on the two beams of 70 per cent or less of that for the simply-supported single beam, and at a combined mass m about equal to that of the single
Beam. As regards deflection, the twin-beam system would tend to be more stiff than a single simply-supported beam of the same load capacity because of the continuity. The labour input for the twin beams would be more, but this alternative is useful when it is desired to reduce the depth of the floor (and thus the storey height), or on long spans where the twin rolled I-sections replace a more expensive single welded plate girder. 


As we have discussed the structure side of a multi-story steel building, now it's time that we discuss about the wall and roof cladding and interior and exterior wall finish and decoration options: 

For the panel, we have our latest foam panel, fiber cement panel. Gypsum board will be a good option for the partition wall. For the ceiling, gypsum, PVC or integrated ceiling are both OK. All these panel options are open to further decorative finish option. 


Our last concern would be the EIFS(EXTERNAL INSULATION FINISHING SYSTEM). Our suggestion would be the integrated insulated decoration panel because it has perfect thermal insulation performance with various pattern and color choices. 

II. Industrial Prefabricated Building. 

Industrial prefabricated building mainly use the structural/pre-engineered steel building system like a warehouse, workshop, hangar or sheds. Here are the introduction on prefabricated steel building system: 

Pre-engineered metal buildings are used for diverse applications such as factories, warehouses, showrooms, supermarkets, aircraft hangars, metro stations, offices, shopping malls, schools, hospitals, community buildings and many more. 

As a leading PMB/PEB manufacturer, KXD provides the complete service of engineering, fabrication and erection thus ensuring better quality control at every stage of the process. 
Pre-engineered metal buildings consists of following components: 

  1. Primary Members / Main Frames
  2. Secondary Members / Cold Formed Members
  3. Roof & Wall Panels
  4. Accessories, Buyouts, Crane System, Mezzanine System, Insulation, etc. 
  5. Sandwich Panels

PRIMARY MEMBERS / MAIN FRAMES

Primary members are the main load carrying and support members of a pre-engineered building. The main frame members include columns, rafters and other supporting members. The shape and size of these members vary based on the application and requirements. The frame is erected by bolting the end plates of connecting sections together. All the steel sections and welded plate members are designed in accordance with the applicable sections as per the latest international codes and standards such as GB and IS to meet all the customer specifications.

CRANE BEAMS

Crane Beams are support members for different type of cranes and allow for unobstructed movement of cranes along the building length. These crane beams are supported on the columns of a building. 

MEZZANINE SYSTEMS
Standard mezzanine system consists of profiled steel deck, mezzanine joists, built-up beams and intermediate support columns. Built-up beams span in lateral directions and mezzanine joists in longitudinal directions bolted to the top flange of beams. A concrete slab is cast on the steel deck as a finished surface. Steel checkered plates can also be used as top surface. 

TRUSSES

KXD Truss System is one of the company's most popular and highly economical products. It is a rigid structure, ideal for large span roof systems, multiple bay buildings and as mezzanine floor framing. These structures are individually designed to meet the specific requirements of each building and are fabricated utilizing high quality efficient fixtures. The system allows for easy erection as all connections are field bolted except for field splices on very large spans, no site welding is required. 
There is possibility of significant reduction in clearances and building heights by running service pipes/ducts through the trusses. Foundation costs are also reduced due to fewer columns being required to support larger spans. 

FASCIAS AND CANOPIES
KXD provides various types of fascias specially designed as per the customer's requirements. These can be either vertical, horizontal or with curved sheeting to enhance the architectural look of the building. Wall canopies at eaves, end wall, over doors and windows are also provided based on the requirement. 

SECONDARY MEMBERS / COLD FORMED MEMBERS

Secondary structural framing refers to purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and other miscellaneous structural parts. 
Purlins, girts and eave struts are cold formed steel members which have a minimum yield strength of 345 MPa (50, 000 psi) and will conform to the physical specifications of GB/ISO/CE or equivalent. 

PURLINS & GIRTS
Purlins and girts are roll formed Z sections, 200 mm deep with 64 mm flanges shall have a 16 mm stiffening lip formed at 45 to the flange. They are supported on columns, rafters or building walls. They can be lapped and nested at the supports which creates a continuous beam configuration. They are placed on the roof and perimeter of the building. Hence they serve as a support to the roof sheeting and wall cladding. 

C SECTION
C-Sections are 200 mm deep with a 100 mm flange. The flanges are perpendicular to the web and have a 24 mm stiffening lip. 

EAVE STRUT
Eave struts are 200 mm deep with a 104 mm wide top flange, a 118 mm wide bottom flange, both are formed parallel to the roof slope. Each flange has a 24 mm stiffener lip. These are located along the sidewall; At the intersection of the planes of the roof and wall. It is constructed from cold formed C-Section and is rolled to suit the roof slope. This member transmits longitudinal wind force on the end walls from roof brace rods to wall brace rods. 

OPEN WEB JOISTS
These are long span load carrying trusses suitable for direct support of floors and roof decks in the buildings. The system consists of crimped angles welded to the top and bottom chords. 

CABLE BRACING
Cable bracing is made of extra high strength seven strand cable and can be designed to accommodate any length to ensure the stability of the building against forces in the longitudinal and lateral direction due to wind, cranes and earthquakes. It is made of a cable which is forged into a rod terminal and this arrangement is then fixed on a structure using a hill side washer, nut washer and a nut.

INSULATED SANDWICH PANELS

INSULATION

The main purpose of insulating a building is to reduce the heat transfer coming through the ceilings and openings. 

Polyurethane Insulation

This is a panel manufactured by the press injection method to produce a polyurethane core between exterior steel facings. It can be used on the roof and wall as claddings. 
Fiber Glass Insulation

This can be used on the roof or wall and can be retrofitted on existing buildings. The fiber glass insulation is fire safe and CFC free and does not emit toxic smoke. It is laminated to the top and bottom steel facings with special chemical glue hence completely filling the insulation cavity. 
SANDWICH PANELS

Six Reasons Steel Buildings Make the Best Warehouses
A warehouse is a great building to own: They're versatile, and can be used for anything from storage to industrial use. But why should you opt for a steel building for your next warehouse? 
1) Maximize Space
One of the best features of steel buildings is that they can be constructed without any interior columns that might take up valuable floor space or interfere with interior operations. The simple fact that machines and laborers do not have to maneuver around massive interior columns can save countless hours of work. It also is incredibly important in maximizing space for storage. 
2) Expansion-friendly
Sometimes clients have told us that they intend to extend their building in future years as their business grows. With steel buildings, this can actually be a very simple process. If the original building was properly erected and well-maintained, you can easily expand it rather than constructing an entirely new structure. 
3)Strong/Durable
We always like to highlight the superior strength and durability of steel over other building materials. Warehouses often are used for commercial and industrial spaces, meaning that they contain heavy objects or heavy machinery that if mishandled can cause significant structural damage. Steel buildings are better able to withstand this type of impact damage. 

4)Resistant to the Elements
Another strength of steel buildings is that they can handle a wide range of environments and climates. They are extremely fire resistant, which makes them the perfect choice if your warehouse stores combustible materials. Furthermore, they are also grounded buildings, and if struck by lightning, can safely disperse the charge into the earth. Steel building are also built with wind exposure in mind to ensure your building will withstand the various wind exposure it will encounter. 
5)Energy Efficient
Energy efficiency is one of the primary concerns of any business owner. You want to make sure that the building is affordable as possible in the future. With steel buildings, it is often important to insulate your building for proper temperature control. Nothing can hurt the efficiency and affordability of a building worse than super-high heating or cooling bills. Lucky for you, metal is reflective, and therefore can reflect heat, making buildings less warm in the hot, sunny months. Another reason metal buildings and roofs can stay cooler is due to the addition of chemicals designed to reflect infrared wavelengths, which can be added to the metal building paint. 
6) Customizable Exterior
Steel buildings are easily customizable in their appearance, and can be designed to fit a certain local or a specific company brand. From eaves to massive garage doors to skylights, we can make sure that your building has the look pictured in your head.
