Prefabricated Steel Construction Factory Light Weight Steel Structure for House Prefabricated Steel Workshop Warehouse Steel Structures Buildinging
Steel structure building is formed by the main framework through linking up the H beam, C purline, Z purline steel components. Roof and wall using a variety of panels together with other components such as windows and doors. The steel building has the advantages of wide span, high strength, light weight, low cost, temperature protection, save energy, beautiful appearance, short construction time, good effect of insulation, long using life, space-efficient, good seismic performance, flexible layout, etc.

FAQ
Pre-sale service
Q1: Can I have a visit to your factory before the order?A: Why not? Welcome to visit our factory. You can fly to Shanghai Pudong Intentional Airport, Hangzhou Xiaoshan International Airport or Wenzhou Longwan International Airport, then come to Lishui railway station through high speed train about 3 hours, 1 hour and 0.5 hour respectively, then we will pick you up at the railway station, hotel booking service is available.
Q2: Do you supply installation service?
A: Yes, we do. But you will pay for our professional installation cost in advance in accordance with the payment term confirmed by both of us, then we will send the engineers and construction workers to supervise it.
Q3: What is a pre-engineered steel structure?
A: Pre-engineered steel structure means that the material is fabricated completely or partially in a factory, ready to be assembled on-site with bolts. There are many advantages to this building type and method. It is much faster than conventional building, as the fabrication takes place within a factory with the use of specialised equipment, and work is not dependant on the weather. On-site construction is also executed much faster, and it is less labour intensive.
Q4: How long can the frame be used?
A: The use life of the main structure is the designed used life, usually is at least 50 years-100 years. (standard request by GB standard)
Q5: How long is the use life of the roof cover?
A: The use life of the PE coating is usually 10-25 years. The use life of roof sun light FRP sheet is shorter, usually 8-15 years.
Q6: What is the anti-rust treatment for steel structure?
A: 12 head large shot blasting machine, shot blasting grade S2.5,
epoxy zinc rich primer,
epoxy cloud iron intermediate paint,
epoxy polyester topcoat.
Q7: Can we construct steel framed house on sea shores or mountains?
A: Steel systems are highly resistant to rust by galvanization process and can be lived safely mountainous areas or seaside areas with intense salt.
Q8: How do we cooperate on certain project?
A: Firstly, please send us your project details, your requirements and design proposal. Then we will make a quotation.Finally we make a deal.
Q9: Is your price competitive with other companies?
A: Our business objectives are to give the best price with same quality and best quality with the same price. We can try the best to cooperate with you to reduce your cost.
Q10: How to get the accurate quotation?
Checking Cost Of steel structure, Please Give Us The Information
(1) Dimension: Length, width, height, eave height, roof pitch, etc.
(2) Doors and windows: Dimension, quantity, position.
(3) Local climate: Wind speed, snow load, seismic magnitude etc.
(4) Insulation material: Panel type, sandwich materials, sandwich thickness
(5) crane metal structures: if have overhead crane, please tell the lifting height and lifting weight.
(6) Is there any materials that are not allowed to import to the country where the structure is planning to use?
(7) If you have other requirements, such as fire proofing, insulated roof, etc. Please also inform us.
(8) It's better if you have your own drawings or pictures. Please send them to us.
Q11: Is a steel structure better than concrete?
A: There are many advantages of steel structures over concrete structures, especially when it comes to structures for commercial, industrial and agricultural environments. In comparison, concrete is able to handle compressive stresses very effectively but it cannot handle high tensile stresses like steel. Concrete can be moulded into any shape, but requires steel reinforcement to increase its tensile strength, preventing cracks and deterioration of the structure. Concrete is also high in self-weight, with steel possessing an excellent strength to weight ratio. Steel structures are easier and faster to construct than concrete structures, and materials are easier to transport.
Q12: What are building regulations in China?
A: Buildings in China need to be designed according to General Specification for Steel Structures GB 55006-2021. You can rest assured that the team from HC will comply with all regulations regarding the design and construction of your commercial steel structure. We comply with the highest quality standards for assurance and will provide you and your company with a safe working environment and comprehensive knowledge in the field of structural steel.
