prefabricated steel structure adopts standardized factory prefabrication and on-site bolt rapid assembly mode, which greatly shortens the project cycle and reduces the foundation cost, providing you with high-strength large-span flexible building solutions. Wedospace is the source manufacturer, eliminating the middleman link, supporting bulk procurement, providing you with highly competitive ex-factory prices and faster delivery speed.
prefabricated steel structure is mainly used in large industrial plants, high-level logistics storage centers, commercial complexes and indoor stadiums.
all steel components are accurately prefabricated and punched in the factory, and directly assembled by high-strength bolts after being transported to the site. Compared with traditional concrete buildings, it can shorten the on-site construction time by about half, helping your project to go into production quickly.
the main steel frame adopts high-strength variable cross-section design, with a maximum span of 180 meters and no internal support columns. This design greatly improves the utilization rate of the internal space of the factory or warehouse, and facilitates the operation of large forklifts and assembly lines.
Since the overall weight of steel is only a small 1 of traditional cast-in-place buildings, the foundation load-bearing requirements and foundation treatment costs are greatly reduced. Standardized factory mass production also greatly reduces material loss and on-site labor costs.
the main body is made of high-quality carbon structural steel, combined with precise mechanical design, the seismic fortification intensity can reach up to 9 degrees. Multi-layer anti-rust primer and topcoat treatment effectively resist wet and corrosive environment, to ensure that the building structure is durable.
the full bolted frame system gives a high degree of flexibility. When the enterprise needs to expand the scale of production in the future, it can quickly increase the span or extend the building structure only by removing part of the exterior wall panel, and the secondary transformation is extremely convenient.
the assembly dry construction process reduces the vast majority of on-site wet work and dust pollution. When the building reaches its useful life or faces relocation, the recycling rate of steel structure main materials exceeds 85%, which meets modern environmental protection standards.
| Parameter name | Specifications |
| Main steel grade | Q235B or Q345B structural steel |
| Main frame connection method | High-strength bolt connection, no on-site welding required. |
| Maximum column-free span | Up to 180 meters |
| Wind resistance level | It can withstand strong winds of level 12 to 14. |
| Seismic fortification intensity | 6 to 9 degrees |
| Corrosion and rust prevention treatment | Two coats of alkyd anti-rust paint or overall hot-dip galvanizing. |
| Roof and wall enclosure | Color steel roofing sheets or polyurethane fireproof and heat-insulating sandwich panels |
| Applicable ambient temperature | -40 degrees Celsius to 60 degrees Celsius |
Suitable for heavy and light manufacturing enterprises that require large areas of barrier-free interior space. The large span provided by the prefabricated frame is convenient for the flexible arrangement of heavy machinery, driving and assembly lines, which perfectly meets the strict load and space requirements of various industrial production.
For businesses that need to quickly set up large storage space. The extremely short construction cycle allows the logistics distribution center to be quickly put into commercial operation, and the highly flexible internal space is very suitable for building multi-layer high-level shelves and wide heavy forklift operating channels.
Suitable for the construction of large supermarkets, exhibition centers or indoor sports venues. The lightweight prefabricated structure not only significantly reduces the cost of deep foundation pit foundation, but also easily realizes the complex and modern architectural appearance design, which perfectly takes into account the beauty and strong practicability.
For construction service providers who undertake the general contracting business of overseas projects. The modular design allows all beam and column components to be standardized and packed into standard containers, which greatly reduces the cost of cross-border shipping, and only requires bolt assembly on site, with very low technical requirements for local workers.
Before pouring the foundation concrete, use a special steel mold to accurately locate the position of the anchor bolts. After concrete pouring and curing, the elevation and axis center point must be carefully re-measured to ensure that the error is strictly controlled within 5mm so as to facilitate the alignment of subsequent columns.
Use a heavy crane to lift the steel column smoothly, accurately align with the anchor bolt holes and fix the temporary spacers. Then the main beam members are hoisted in turn, and the high-strength bolts are used for preliminary connection, and the verticality correction is carried out with the theodolite.
After the main frame is fully aligned and locked, cross bracing between columns and roof horizontal braces are installed in turn. Subsequently, the roof and wall purlins are fixed with bolts to completely form a multi-dimensional force, stable and wind-resistant overall load-bearing skeleton.
From the bottom of the building from the bottom of the laying of external wall insulation board, and then complete the roof panel lap installation. All plate joints shall be sealed with high-quality weather-resistant adhesive, and rain-proof edge wrapping angle and drainage gutter system shall be installed in accordance with the specifications.
