The GAOERJI 20 × 20 steel building is mainly used in industrial park security guard room, on-site temporary office, equipment and instrument storage room and small spare parts warehouse.
20 x 20 steel building Features
Weld-free all-bolt module assembly:
The structural components are pre-perforated with high precision in the factory, and the corrosion-resistant bolts are directly fastened and connected on site, eliminating the on-site electric welding operation by 100%. The construction period is shortened by more than 60%, greatly reducing the cost of local labor installation.
high strength anti extreme climate design:
After strict structural calculation, the 20 × 20 steel building has a wind resistance of 225 kilometers per hour and can withstand a snow load of 1.4千帕 per square meter, effectively ensuring the safety of equipment and personnel in harsh weather environments.
high precision intelligent cnc manufacturing:
The factory is equipped with high-power CNC laser cutting machine and cold bending forming production line, and the dimensional tolerance of components is controlled within 0.2mm. The extremely high assembly accuracy ensures zero error of on-site assembly and prevents water leakage in the later period of traditional small houses.
long-term galvanized double antirust:
The skeleton and outer plate are made of high-grade steel plate with double-sided hot-dip aluminum-zinc plating layer reaching 150g per square meter, which improves the anti-corrosion and anti-rust ability by 4 times in atmospheric environment and provides long-term paint-free anti-rust protection for more than 50 years.
high space utilization without column structure:
Designed with a self-supporting frame and no intermediate columns, the 400-square-foot interior space is 100 percent barrier-free, providing great convenience for forklift rotation, material stacking or on-site office equipment arrangement.
One-stop engineering deepening design docking:
Gorky has a team of more than 30 professional design engineers who use professional steel deepening software to provide contractors with detailed drawings that comply with local building regulations and ensure that 100 per cent of the drawings are approved by the local government.

20 × 20 steel building contrast point
In the field of engineering matching and modular construction, traditional small houses are often rough on-site welding and manual cutting due to lack of precision, which not only lengthens the construction period, but also easily produces rust and cracking at the weld. In contrast, the 20 × 20 steel building produced by GAOERJI is manufactured by modern high-precision numerical control machine tools from skeleton cutting to plate forming, and the hole tolerance of the components is strictly limited to 0.2mm. This means that the contractor does not need to perform any secondary cutting or reaming when assembling on site, which greatly improves the construction efficiency. In addition, in terms of anti-corrosion and weather resistance, GAOERJI also show significant technical vertical advantages. The common light steel structure buildings on the market often use ordinary low-density hot-dip galvanized steel, which starts to rust in 3 to 5 years in a humid or industrial salt spray environment. In the manufacture of 20 × 20 steel building by Golgi, the core color coated plates were all upgraded to double-sided hot-dip aluminum-zinc plating process. Compared with ordinary hot-dip galvanized color plates, the anti-corrosion performance was improved by more than 4 times, which can ensure that the building does not need frequent surface painting and rust prevention in the service life of more than 50 years.
Field construction without power on-site welding inconvenience:
Field projects often face temporary power shortages. The GAOERJI provides a full set of factory high-precision pre-perforated components, which can be formed by simply manually tightening the bolts on site, eliminating the use of high-power electric welding machines.
Small size housing components packaging chaos scattered:
Contractors often cause on-site leakage and missing parts due to bulk shipments from manufacturers. GAOERJI the implementation of fine module packaging, bolts, seals and corresponding steel parts classification packing, to prevent the lack of parts due to delay in the progress of the project.
High winds and heavy rain weather cause water leakage in wallboard joints:
Traditional board room often seams leakage in heavy rain. The GAOERJI adopts double protection design of precision lock buckle and waterproof high elastic sealing strip, and keeps the interior dry under heavy rainfall of 100mm per hour.
20 × 20 steel building for people
industrial park and logistics real estate general contractor:
Engineering procurement teams for security kiosks, small equipment distribution rooms or monitoring rooms need to be quickly deployed in the park and plant. The GAOERJI standardized components can realize synchronous planning and efficient assembly with large projects.
Municipal infrastructure and road construction contractors:
It is necessary to establish a safe, durable, wind-resistant temporary headquarters, material warehouse or employee lounge unit at the construction site. The product can be quickly disassembled and used many times, and the extremely high recovery reuse rate can greatly dilute the construction cost.
Oil and gas and energy system integrators:
Integrators who need to erect instrument measuring rooms, cabinet shelters or valve chamber canopies in remote mining areas and gas wells. The high-grade weather-resistant and sealed dust-proof structure provided by Golgi can ensure the smooth operation of high-precision equipment in harsh environments.
Communication base station and distribution network construction subcontractor:
A telecommunications subcontractor who needs to quickly build a small equipment protective house next to the tower. The product can complete the main body assembly in one day, greatly shorten the construction period of the base station, and the double-layer galvanized corrosion-resistant plate can ensure maintenance-free within 50 years.
20 × 20 steel building instructions
Foundation pouring and position retest:
Complete the concrete leveling foundation pouring according to the drawings, and retest the diagonal of the four corner points and the bolt embedded slot to ensure that the error is within 2mm.
Frame assembly and column leveling:
Assemble steel beams, columns and connecting beams on the ground in turn. After erecting the steel frame, adjust the verticality with a level and lock it with high torque double-headed anti-loosening bolts.
Laying of wall and roof slabs:
High-strength color-coated enclosure steel plates are installed from one side to the other in turn, special high-elasticity waterproof sealing strips are laid at the joints, and self-tapping fasteners are used for reinforcement.
