GAOERJI STEEL
Search
GAOERJI 30×30 steel building is constructed from high-strength Q345B steel and designed through professional Tekla modeling to provide approximately 84 square meters of open, column-free space, combining excellent structural stability and durability. GAOERJI is a source manufacturer with intelligent manufacturing equipment such as 12000W high-power laser cutting, eliminating middlemen and providing you with highly competitive factory prices and faster delivery speeds.
30×30 steel building is mainly used in industrial production workshops, small logistics warehouses, commercial retail exhibition halls and equipment storage warehouses.
Three-dimensional modeling using Tekla Structures and 3D3S ensures that the hole position of each component of the 30×30 steel building is accurate to the millimeter level, and no secondary drilling is required for on-site installation.
Q345B high-strength low-alloy structural steel is selected, which has high tensile strength. Compared with ordinary carbon steel, the structural load-bearing capacity is increased by more than 20% with the same amount of steel used.
12000W high-power laser cutting machine and CNC automatic welding line are put into use, the cutting end face is smooth and burr-free, ensuring the fatigue life and welding quality of steel structural components.
For the use environment of 30×30 steel building, it is provided with double-sided epoxy zinc-rich primer or deep hot-dip galvanizing treatment, and the anti-corrosion coating thickness is standard to effectively resist rust erosion.
With more than 30 senior design engineers, we have full-process control from plan drawings, deepening drawings to production and processing to ensure that overseas customers receive professional remote guidance during the installation stage.
All building components are prefabricated in the factory and adopt a fully bolted connection mode, which can shorten the construction period by 60% compared with traditional concrete buildings and significantly reduce on-site labor costs.
| Technical indicators | Detailed specifications |
| Main framework | Welded H-beams / Hot-rolled H-beams (Q345B) |
| Secondary component system | C-type or Z-type purlins, tie rods, and corner braces (Q235B) |
| Roof and walls | Corrugated steel sheet/sandwich composite panel (EPS, rock wool, glass wool) |
| Windows and doors | Aluminum alloy windows / Industrial sliding doors / Roller shutters |
| Design load standard | Customized calculations based on local wind load and snow load. |
| Implementation Standards | Compliant with ISO9001:2008, SGS, CE, and BV certification standards. |
| Connecting fasteners | 10.9 grade high-strength bolts and ordinary bolts |
| Drainage fittings | Color steel water trough, PVC downpipe and related accessories |
Provide low-cost, high-quality 30×30 factory space for start-up factories that need to quickly establish production lines to meet the layout needs of basic production equipment.
Suitable for the rapid deployment of small distribution points or material turnover warehouses in specific areas. The fire resistance and anti-theft properties of steel structures provide security for goods.
The 30×30 open span is ideal as an auto repair shop or small shopping mall, facilitating flexible layout of internal booths and lifting equipment.
For steel structure suppliers who need to comply with international certifications (such as CE/SGS), GAOERJI provides one-stop design, production and global logistics services.
Concrete pouring was carried out strictly in accordance with the foundation drawings provided by GAOERJI to ensure the precise placement of the anchor bolts.
After the goods arrive at the scene, they are sorted according to the list to ensure that the coating paint is intact and stacked in the order of installation.
Use lifting equipment to connect the columns and beams in sequence according to the drawing numbers, first perform preliminary fastening and then perform overall correction.
When installing wall panels and roof panels, pay attention to the overlapping direction and use matching sealant to ensure the overall waterproofness of the building.
