Case 1: steel structure stereoscopic structure (3D design, 3D visual)

B. Natural conditions and working load

1. wind velocity pressure: 0.55 KN/M

2. Load on structures

(1) The steel structure computation procedure will calculate and input the steel weight.

(2) Dead-load: 0.6 KN/M

(3) Live load: 0.5 KN/M

Case 2: outdoor dual pillar led display steel structure

C. Requirements on the steel structure design material

1. Steel members adopt Q235B party (flat) steel pipe and hot rolled steel channel.

D. Derusting, anti-corrosion measures on led display steel construction:

1. Durable life of anti-corrosion coating should be more than 15 years.

2. Derusting, anti-corrosion measures on the steel structure: sand derusting Sa 2.5 on the Richter scale; two red lead primer (100 um), alkyd paint (50 um).

Case 3: single pillar outdoor led display steel structure design sketch:

E. production and installation requirements of the steel structure design

1. all the steel components should be produced and processed by factory, the production and installation of steel structure should comply with relevant rules for steel structures.

2. the lofting, marking, cutting, straightening, molding, edge processing, node processing,system hole and assembly of the steel structure should meet the requirements of GB50205- 2001.

3. The cutting of the steel members should be based on the geometry of each node so as to match the various groove shapes of different nodes. The size of the grooves should comply with the requirements for the nodes weld. 4. Welding methods are manual arc welding on three sides and on the corner it must be continuous welding.
