Product Description

Product Description

Quality galvanized steel structure materials hot rolled H-shaped steel angle steel square pipe round pipe purlin

The special steel for prefabricated steel structure is mainly "modular adaptable steel", supplemented by special steel parts, corresponding to the core needs of prefabricated construction, and the common categories are as follows:

High-precision H-shaped steel: The dimensional tolerance of section size is controlled within ±0.5mm, the deviation of the verticality of the flange and the web ≤0.3°, and the standardized bolt hole reserved on the surface, which is the "core load-bearing unit component" of the prefabricated steel structure. It is often used for the column of modular construction and main load-bearing beam of the prefabricated factory building, and can be directly assembled with other modules through high-strength bolts, without the need for secondary drilling or cutting site.

Cold-bent thin-walled channel steel: made of Q355ND low temperature toughness steel by cold bending, with a wall thickness of2.0-4.0mm, the section is a "channel" structure with reinforcement ribs, which is the "enclosing support component" of the prefabricated steel structure. It is often used for the keel of modular partition walls and the purlin of roofs, and can be assembled quickly with color steel plates and light wall through snap-in connectors, and can be reused after disassembly.

High-strength bolt connection steel plate: made of Q460GJC special steel for highrise buildings, with a thickness of 8-30mm, the surface roughness of the steel plate is controlled at Ra12.5μm, which is thenode core connector" of the prefabricated steel structure. It is often used for the end plate and lifting ear plate of the modular unit, which can withstand repeated lifting and-term load, and the bolt hole is surrounded by a preset stress relief groove to avoid stress concentration during assembly.

Demountable angle steel: with an isosceles section, both ends of the angle steel are pre-drilled with positioning and bolt holes, with a positioning accuracy of ±0.1mm, which is the "auxiliary component" of the prefabricated steel structure. It is often used for diagonal bracing of modular frames and temporary fixed supports, and can be quickly aligned through positioning studs installation, and there is no residual damage after disassembly, which can be adapted to the reorganization of modular units of different specifications.

Weather-resistant corrugated steel: made of Q500NQR1 weather-resistant steel by roll forming, with a wave height of 30-50mm, and a surface with a-weathering rust layer, which is the "enclosing panel base material" of the prefabricated steel structure. It is often used for the walls of prefabric venues and the roofs of temporary buildings, and can be directly fixed on the cold-bent steel keel by bolts, with an installation efficiency 50% higher than of ordinary color steel plates, and no need for later painting maintenance.

Product Advantages: 

I-shaped steel, with its unique sectional design of "wide flange and thin web", has a significantly higher moment inertia and section modulus than I-beams and channel steels of the same specification, offering stronger resistance to bending moments. The flanges and webs work together to effectively disper loads and avoid local stress concentrations. It provides stable and efficient load-bearing support for structures, especially suitable for large-span and heavy-load engineering scenarios.

I- steel is mostly hot-rolled in factories with a straightness error of ≤1mm/m and a sectional size accuracy of ±0.5mm. No secondary correction required on-site, and it can be directly cut and drilled. The interchangeability of components is strong, greatly reducing processing losses. In the installation process, the I-shaped has a flat flange, which facilitates connection with other components through welding or high-strength bolts, with ample operating space and no need for complex tooling. Moreover, it more than 60% lighter than concrete components of the same bearing capacity, making it easier to transport and hoist, reducing mechanical usage costs and construction cycles, and perfectly meeting needs of modern steel structure engineering for industrialized and prefabricated construction.

The sectional form of I-shaped steel is flexible, and different specifications can be selected to engineering needs, with varying flange widths and web thicknesses. It can accurately match the stress characteristics of different parts, avoid material waste, and reduce overall steel consumption. In, the surface of I-shaped steel is flat, without complex grooves or dead ends, which facilitates anti-corrosion treatment (such as brushing anti-corrosion, hot spraying zinc), with strong adhesion and uniform coverage of the coating. In an ordinary atmospheric environment, after regular anti-corrosion treatment, the service life exceed 50 years. Even in humid or slightly corrosive environments, with weather-resistant steel materials (such as Q460NQR1 I-shaped steel) it can maintain stable performance without frequent maintenance, taking into account the economy of the project and the durability of the structure.
