Product Introduction

Steel structure products refer to various products made of steel materials, which have the advantages of high strength, light weight, good seismic performance, and strong industrialization. They are widely used in many fields such as construction, machinery, and transportation.  The following is an introduction to some common steel structure products:

Steel Structure Buildings

Light Steel Structure System: It mainly adopts a light - weight solid - web member portal frame structure system, generally with 1 - 2 floors.  This type of building has a large - plane space, flexible division, and good economy.  The usual height is 3 - 8 meters, the clear span is 9 - 100 meters, and the roof slope is 1/48 - 1/4.  It is especially suitable for building various low - rise light - industrial factories, logistics warehouses, and other industrial buildings, as well as large - scale supermarkets, stores, cold storage, and other commercial buildings.

Heavy Steel Structure System: Developed on the basis of the light steel structure system, this type of building is generally equipped with a heavier traveling system and mainly adopts a heavy - duty portal frame structure system.  It has a large - plane space and good economy, and is particularly suitable for building various low - rise heavy - industrial factories, such as heavy - chemical plants, power plants, shipyards, and heavy - machinery manufacturing plants.

Multi - layer Steel Structure System: It mainly uses a steel frame structure and adopts a composite floor system, mainly using metal and glass enclosure materials.  

Compared with the traditional reinforced concrete structure, this system has great comprehensive performance advantages and can provide a spacious plane space.  It is especially suitable for building modern multi - storey and high - rise industrial plants, office buildings, commercial centers, three - dimensional supermarkets, three - dimensional garages, teaching buildings, student apartments, and multi - storey and high - rise residential buildings.

Long - span Space Steel Structure: It refers to steel frames, latticed shells, truss structures, and their hybrid structures composed of two or more different building materials.  This is a type of space structure system with reasonable stress, large stiffness, light weight, simple components, and convenient manufacturing and installation.  In the past one or two decades, it has developed vigorously and has been widely used in public and industrial buildings such as large - span and large - column - grid stadiums, stations, convention and exhibition centers, theaters, and factory buildings.

Special Steel Structure System: It mainly includes various space lattice structures, cable - membrane structures, tower structures, keel structures, and other special - shaped structures.  This type of product generally has a special purpose or a particularly complex shape, and the single - unit scale is generally not too large, but the design, manufacturing, and installation are very difficult.  It is suitable for building various clubs, exhibition halls, sales centers, commercial buildings in scenic areas, urban decorative buildings, and creative office and catering centers.

Production process

FAQ

What is the minimum order quantity for steel structures?

Twenty tons.

How long is the processing cycle for steel structures?

Orders of 300 tons usually take 20 days to be dispatched.

How many types of cooperation models are there?

a. Process and manufacture according to the design drawings; 

b. Based on the other party's building area and usage conditions, carry out steel structure design. After confirmation by the other party, process and manufacture according to the drawings. For large-scale projects, technicians can be arranged to provide on-site installation guidance.

Processing scope of steel structures

Steel structure portal workshops, exhibition halls, sports stadiums, residences, Bridges and other components can all be processed.

Occasionally, surface defects, internal cracks, inclusions and other issues may occur in the raw materials of steel structures. How do we ensure the quality of the raw materials?

Strict acceptance: When making purchases, it is necessary to select suppliers with good reputations and conduct strict inspections on the materials arriving at the site, including tests for chemical composition and mechanical properties.

Material inspection: Conduct a comprehensive material inspection before processing to ensure that the materials comply with the design and construction specifications.

Record and track: Establish quality files for materials and conduct tracking management to ensure that qualified materials are used during processing and construction.

How did we solve the problem of deviation in the processing accuracy of steel structures?

Cutting: Use high-precision cutting equipment and calibrate the cutting machine regularly to ensure the accuracy of the cutting dimensions.

Control the heat input during welding: Select appropriate welding processes and parameters, and adopt measures such as preheating and post-heating to reduce deformation during the welding process.

Processing inspection: During the processing, the dimensions and shapes of the processed parts should be inspected regularly, and the processing parameters should be adjusted in a timely manner to control the accuracy.

During the installation of steel structures, problems such as bolts being too loose or too tight often occur. How do we solve these issues?

Pre-assembly inspection: On-site dimensional measurement and inspection are carried out before assembly to ensure the fit accuracy of each part.

Establish standards: Clearly define the tightening specifications and torque requirements for bolts, and use tools such as torque wrenches to ensure that the tightening torque complies with the standards.

Train workers: Provide training to on-site construction workers to enhance their assembly skills and quality awareness.

The anti-corrosion coating of the steel structure is substandard, which can easily lead to the corrosion of the steel. How did we solve this problem?

Use qualified coatings: Select qualified anti-corrosion coatings and apply them in accordance with the coating specifications to ensure the quality of the coating.

Anti-corrosion treatment: Rust removal treatment is carried out on the steel, and anti-corrosion treatment is conducted before processing to enhance its corrosion resistance.

Environmental protection: Measures should be taken at the construction site to protect steel and prevent it from being exposed to harsh environments for a long time.
