You ONLY need you to provide us with the following information:

Design Parameters:
1) Live load on roof (KN/M2);
2) Wind speed (KM/H);
3) Snow load (KG/M2)  - If Applicable;
4) Earthquake load - If Applicable;
5) Style of Doors and Windows;
6) Crane (if you have), Crane span, Crane lift height, max lift capacity, max wheel pressure and min wheel pressure; 
7) Size: width X length X eave height, roof slope;
8) Or your idea!
BUT maybe you are unsure about what type or what needs you have regarding you're warehouse/workshop, or this project is your first one. Don't worry, we will teach you to choose the right style and the finest design within your budget.
