1. The content of steel structure mainly includes the load-bearing structure of the greenhouse and the support, connecting parts and sturdy parts to ensure the stability of the structure. 2. Materials and Construction Precautions The steel structure is mainly made of cold-formed thin-wall steel and hot-rolled steel. Except for a few components made of high-strength steel, the rest are made of A3F. Glass greenhouse steel skeleton is generally produced by professional chemical plants. Because the greenhouse components are in the indoor high humidity environment for a long time, all structural components should be anticorrosive treatment. It is usually treated by hot dip galvanizing. In order to ensure the effect of anti-corrosion treatment, all components should be processed before anti-corrosion operation. Cutting, sawing, welding and other operations on the greenhouse components are not allowed on site. If there is a small amount of on-site operations, it is also necessary to carry out anti-corrosion reinforcement treatment, spray anti-corrosion paint on the processing or wound. Skeleton installation shall be carried out in strict accordance with the drawings and relevant standards, specifications and regulations. At present, China has completed the industry standard of the main structure of double slope glass greenhouse 0, which can be used as one of the bases for the construction of glass greenhouse steel structure after it is officially promulgated. At this stage, the construction mainly uses GBJ*****5 steel structure design Code 6 and GBJ*****5 cold-formed thin-wall steel structure technical Code 6 as the main construction reference.


Folded aluminium alloy
1. Functional aluminum alloy as the main inlaying and covering supporting member of glass greenhouse, its main functions are :(1) with rubber seals, as a part of the sealing system of glass greenhouse covering; (2) used alone, as a greenhouse roof supporting member and sealing member; (3) Used as a gutter.

2. The main part of the design requirements mainly meet the requirements of strength and stiffness; The support part as the glass support is mainly reserved for some through the length of the support groove or inlay groove; The inlay part located on the outside of the glass shall be provided with a groove specially for installing the rubber seal, which can be used to fix the rubber seal, or with small aluminum alloy or stainless steel parts to fix the glass.
