What specifications are used for the steel structure of the 10*10? Do I have to use I-beam? Will the iron square be all right?
Square steel tube is good, both beautiful, anti-corrosion costs and bottom. The base square steel pipe must be closed, otherwise it will be difficult to deal with corrosion from the inside.
Square tube can be, but it is better to buy GB material, otherwise the wall thickness is too thin, can not meet the design requirements ~!
10X10 this annotation method is not standard marking, can not see what type is. Considering the stability, the square pass is much better than the weak axis of i-beam. The advantage of I-beam is light weight and small amount of steel, but if the area is small, the difference between the two is small, and the other is convenient construction. Depending on how big the two directions should be used, the thickness should not be less than 4MM if welded. To two spans around 2.5M, for example, the glass to consider the point weight of 0.5KN/, each flat, using B120X80X5X5 (high 120mm, width, 80mm, thick, 5mm) material, Q235B GB steel is more appropriate. If you have more snow areas, you can use B140X90X5X5.
