fabricated steel structures for mining and construction contrast points
As a senior manufacturer of prefabricated mines and building steel structures, GAOERJI is committed to solving the problem of lengthy on-site construction cycles through precision factory prefabrication. We not only have a team of more than 30 design engineers for high-precision control, but also provide a complete closed-loop service from material processing to overseas installation guidance to ensure that the building body can withstand the vibration and harsh weather of the mining area.Compared to traditional traders and small-scale processing plants, GAOERJI in heavy-duty and anti-corrosion process has a more stringent control. We directly meet the terminal requirements, relying on the automated H-beam production line and high-standard non-destructive testing technology, while providing high-precision components, it greatly reduces the user’s secondary modification and later maintenance costs.
The remote installation efficiency of the project site is low
for remote mining areas with inconvenient transportation and lack of skilled workers, we adopt the weldless assembly design of full bolt connection and cooperate with professional on-site guidance to reduce on-site labor costs.
Structural fatigue caused by vibration of heavy mining machine
in the face of high-frequency vibration equipment such as crushing and screening, we optimize the node design and improve the weld flaw detection standard to prevent cracking and failure of steel frame joints caused by long-term vibration.
Acid rain and high humidity environment in mining area are easy to rust
for high corrosion mining area, we provide hot dip galvanized or heavy anti-corrosion coating with a thickness of more than 85 microns to block the erosion of harmful media on the steel substrate.

fabricated steel structures for mining and construction instructions
Re-test and acceptance of foundation
before the components are delivered to the site, re-test the foundation axis, elevation and spacing of embedded parts with theodolite to ensure that the deviation is within the specified tolerance range.
Classification of components and preparation for hoisting
place steel columns, steel beams and supporting components in different areas according to the packing list, clean the surface of connecting plate before hoisting, and prepare high-strength bolts.
Hoisting and preliminary calibration in order
hoisting shall be carried out in the order of first steel column, then main beam, first middle and then both sides. After the member is in place, temporarily fix it with cable wind rope and preliminarily correct the verticality.
Bolt fastening and final calibration
the joint high-strength bolts are initially and finally tightened to achieve the design torque. Subsequently, the overall structure of the steel frame will be finally calibrated, and the pouring will be completed after confirmation.

FAQ And Contact Us
Welcome to our Frequently Asked Questions page. We have compiled answers to common questions you may have, hoping to provide you with clear and quick solutions. If you cannot find the information you need here, please feel free to contact our customer support team.
Question 1: How to ensure that the fabricated steel structure is not damaged and rusted during ocean transportation?
Answer: Our components will be classified and packed, and rubber pads will be installed on vulnerable parts. The surface is treated with hot-dip galvanized or long-term anti-corrosion paint, and the sea container is bound and fixed to effectively prevent salt spray corrosion and collision.
Question 2: How to guarantee the stability of steel structure in the face of severe vibration of heavy mining equipment?
Answer: In the design, we will use the dynamic load factor for structural calculation, strengthen the secondary beam and diagonal brace at the support part of the equipment, and all use high-strength bolt connection, so as to absorb and disperse the stress caused by high-frequency vibration.
Question 3: Can you provide detailed design and drawing verification services for steel structures?
Answer: Yes, it is possible. We have a professional steel structure design team, using professional design software for high-precision modeling, which can seamlessly connect the original drawings provided by customers and avoid construction conflicts in advance.
Question 4: What if our construction team has no experience in steel structure assembly during on-site construction?
Answer: We not only provide detailed assembly construction drawings and corresponding coded components, but also send engineers with rich overseas experience to the site to provide full installation guidance and technical training.
Question 5: What is the overall seismic and wind resistance of the fabricated steel structure?
Answer: Our products mainly use high-strength structural steel. According to different project locations, the design seismic intensity can reach eight degrees, and the wind load can withstand 12 strong winds to ensure safety and stability in severe weather.
Question 6: How long will it take from the order to the final delivery of the product?
Answer: The production cycle depends on the size of the project and the complexity of the design. After the drawings are confirmed, the steel structure of the medium-sized mine workshop is usually processed within 30 to 45 days and has the factory conditions.
Please feel free to contact us. We look forward to hearing from you.
