Product Description

Product Information
Structural beam warehouse steel structural building also called Pre-Engineered Metal Buildings (PEMB) or simply Engineered Metal Buildings (EMB) is a steel structure built over a structural concept of primary and secondary members, and roof sheeting connected to each other. The structural members are custom designed to be high in strength as well as lighter in weight.
At present Steel is the material of choice for all in building construction, compared to concrete and timber. Thus steel building designs have become more flexible, durable and adaptable. In future too the choice of steel building will have the same effect as on today.

A.Structural Beam Warehouse Steel Structural Building CONSISTS OF FOLLOWING MAIN COMPONENTS::
Primary Sections Column,Rafters
Secondary Sections Purlins, Tie rods, Eave Strut, Rake angles, Girts
Cranes and Mazzanines.
Roofing and Cladding Roof Panel and Wall Panel
Accessories Canopy, Turbo Vent, Ridge Vent, Gutters, Crane Runways,
Insulations, Louvers, Roof curb, Sealants, Fasteners etc

B.USE OF STRUCTURAL BEAM WAREHOUSE STEEL STRUCTURAL BUILDING
PEB concept has been very successful and well established in North America, Australia and is presently expanding in U.K and other European countries. PEB is ideal for construction in remote & hilly areas due to its low cost and fast completion. PEB concept has acted as a catalyst in the infrastructure development of the country. Single storied houses for residential purposes take minimum time for construction and can be built in any type of geographic location like extreme hot, extreme cold hilly areas, high rain prone areas, plain land and seismic zones etc. The PEB rigid frame comprises of built-up members with tapered or straight columns and tapered rafters. The frame is erected by bolting the end plates of connecting sections together.

C.APPLICATION
STRUCTURAL BEAM WAREHOUSE STEEL STRUCTURAL building systems finds primary application in construction of Warehouses and construction of Industrial Buildings. The recent focus has also shifted to cover Rural as well as urban, individual and mass housing projects, farmhouses and slum rehabilitation projects.

Application of pre-engineered steel buildings has also included the following:
PEB Structures are fabricated to the end user's requirement in a factory and erected at site, which leads to saving of time.
PEB is ideal for Factory Buildings, Warehouses, Aircraft Hangars, Indoor Stadiums, Fuel Stations, Metro Stations, Bus Terminals, Parking Lots, Schools, and Outdoor Stadiums with canopies where the intermediate columns are to be avoided.
PEB is ideal for Show Rooms, Office Complexes, Commercial Complexes & Supermarkets.
PEB is ideal for Labour Camps, Community Centers, Equipment housing , Telecommunication shelters, Airports, Railway Stations & Railway Storage yards, Exhibition Halls etc. due to its aesthetics look.
PEB is ideal for buildings in City Area where land cost is too high.
PEB is ideal for buildings that need to be relocated to other places.
PEB is ideal for buildings that are to be built faster.

I.Steel plate cutting
The H section  steel plate should be checked again by the factory and shall be applied under the condition of up to design and specified requirements after checking. Steel plate cutting should be aimed at quality guarantee and material saving. For each process like plate cutting,H type assembly, components assembly and pre-assembly should be carried out by profession setting-out worker precisely on processing surface and assembly sample plates.To guarantee the accuracy of the components'geometrical dimension,tolerance of form and position, angle and contact surface,inspection is necessary by inspector after setting out.In order to ensure the cutting quality,the surface of the ultra-thick plate is subjected to the surface carburizing hardness test before cutting.The CNC cutting equipment is preferred for cutting.The high purity 98.0% acrylic gas and 99.99% liquid oxygen gas are used to guarantee the smoothness and flatness of the cutting surface without notches and slags.The groove is cut by a special imported cutting machine.

Process, fabrication and quality control standard on welding groove/beveling of steel structure
1. Purpose
To ensure the welding quality, meeting up the technical requirements of welded members and improve the standardization of our fabrication, we specially formulate this regulation.
2. Application scope
This manual apply for the design, fabricate and inspection of groove joint in terms of manual arc welding, CO2 arch welding, mixed gas arch welding, submerged arc welding and electroslag welding.
3. Design of welding groove
3.1 Key points on design welding groove:
In order to obtain quality groove, it is necessary to choose appropriate form of groove. The option of groove mainly depends on the thickness of base metal, welding method and craftsmanship requirements.The followings are the factors we need to consider:

1. minimize the amount of filler metal
2. easy for beveling
3. in convenience for welding operation and slag removal
4. After welding stress and deformation should be as small as possible

3.2 Groove direction:
We will consider the following factors for the groove direction:
A)in favor of welding process and removing slag and leave enough space for welding process on the fusion face
B)minimize the times of flip-flop during welding
C)way of fit-up in actual welding

3.3. Regulation on groove direction of members:

3.3.1 Butt welding on H section rafter/column (when CJP-complete joint penetration and single side fusion is required)
1) When there is no welding backing, the groove orientation on flange plates should be same and falls on the direction in favor of welding on web plats(same rules apply for the PJP situation). Please refer to illustration 1

2)When there is welding backing, we require the groove direction being outward for the flange plates(opposite direction for web plates) and still falls on the direction in favor of welding on web plates. Please refer to illustration 2
3)Butt-welding on construction site:we require all the grooves should be bevelled on the upper rafter/column when it comes to bolt connection for web plates(see illustration 3). For the scenario of welding on web plates, please refer to the illustration 4.
3.3.2 Box column(groove on itself).See illustration 5
4. Welding groove form
4.1. Mark on form and size of welding joint groove:
Example: Shielded metal arch welding, complete joint penetration, butt welding, I shape groove, welding backing and single side weld would be marked MC-BI-BS1
