Yield Strength Grade	235	345	390
Ceq(%)	≤0.36	≤0.43	≤0.45
Note: In order to improve the performance of steel,390 could add the microelement such as V, Nb, Ti, Mo and N etc.

2). Mechanical Property:

3). ⅠGrade Product Yield Strength:

Yield Strength Grade	Outside perimeter (mm)	Wall Thickness (mm)	Yield Strength %
			Directly to Square	Round to Square
235	≥800	12~22	≤80	≤90
345
390			≤85	≤90
Note: when the outer perimeter less than 800mm,can be determined by supply and buyer

Advanced machines:

If you really interested in our steel structure workshop drawings, and would like we do the design for you, please give me the following information:
1. Dimension: Length, width, height, eave height, roof pitch, etc.
2. Doors and windows: Dimension, quantity, position to put them.
3. Local climate: Wind speed, snow load, etc.
4. Insulation material: Sandwich panel or steel sheet.
5. Crane beam: Do you need crane beam inside the steel structure? And its capacity.
6. Is there any materials that are not allowed to import into the country where the structure is planning to use?
7 .Any requirements let me know we will do the best.Certainly if you can provide us the drawing which you are need is the best.
