Prefabricated assembled steel beams

Description

Prefabricated steel beams for prefabricated steel structures are becoming increasingly widely used in modern construction and bridge engineering due to their advantages of high strength, lightweight, and fast construction.

Prefabricated steel beams for prefabricated steel structures are usually made of high-strength steel, such as Q355B, Q420C, or steel that meets standards such as ASTM A572 Gr.50. These steels have high yield strength and tensile strength, which can meet the structural requirements of large-span and heavy loads.

The manufacturing process mainly includes:

Automated cutting and cutting: using CNC plasma cutting and other processes, with high precision (tolerance can be controlled within ± 1mm).
Automated welding: Widely using automated welding processes such as submerged arc welding (SAW) to ensure stable and reliable weld quality.
Anti corrosion treatment: According to the usage environment, hot-dip galvanizing (such as average zinc layer thickness ≥ 85 μ m), or coating with multi-layer anti-corrosion systems such as epoxy zinc rich primer, epoxy cloud iron intermediate paint, and polyurethane topcoat, can be used. The design service life can reach more than 50 years.

Structural characteristics and connection methods

The significant features of prefabricated assembled steel beams are modular design and efficient connections.

Product Details

Steel structural beams are made of high-strength steel and undergo precise cutting, welding, and anti-corrosion treatment (hot-dip galvanizing or multi-layer coating system) through automated production lines. This product has excellent mechanical properties, with a yield strength of ≥ 355MPa and a tensile strength of 470-630MPa. It supports large-span design (up to 60 meters), meets seismic resistance requirements of 9 degrees, and reduces weight by more than 40% compared to concrete structures. The prefabrication rate of its factory is over 85%, significantly reducing the on-site construction period, and achieving rapid installation and later expansion through modular design. The product is widely used in industrial plants, commercial buildings, bridges, and subway stations, balancing safety, efficiency, energy conservation, environmental protection, and full lifecycle cost advantages.

Advantages

1.High strength and lightweight:

Compared to concrete structures, steel structures can reduce their own weight by 30% -50%, significantly reducing foundation loads and costs.

2.Fast and efficient construction

 Factory prefabrication and on-site assembly can be carried out in parallel, which can shorten the overall construction period by more than 50%.

3. Stable and controllable quality

 The factory production environment is stable, the process parameters are precise, and the product quality is easier to control.

4.Environmentally friendly and sustainable

Steel can be 100% recycled, and the carbon emissions during the construction process are lower than those of concrete structures.

5.Excellent seismic performance

The steel has good ductility, and after reasonable design, the nodes can meet the seismic fortification requirements of high-intensity earthquake zones.

Application scenarios

Prefabricated steel structures that can be assembled with steel beams are widely used in:

1.Industrial and civil buildings

 such as factories, warehouses, large supermarkets, sports halls, and other large-span buildings.

2.Bridge engineering

 Whether it is highway bridges, railway bridges, or urban overpasses, the presence of prefabricated steel beams can be seen, and their large-span capacity can effectively reduce the number of bridge piers.

3.Other fields

 It can also be used for platform structures, overhead pipeline supports, modular buildings, etc.
