Hot-rolled steel structural material H-shaped steel purlin sandwich panel high

Product Specification

High-strength hot-rolled galvanized steel structural material H-shaped steel purlin sandwich panel high-strength bolts

Steel structure materials are the core system of steel structure buildings, with steel as the base, which can be divided into three categories according their functions: main load-bearing materials, enclosure materials and auxiliary protective materials. It has high strength, high adaptability and flexibility of scene, and is the preferred choice for largespan and high load-bearing buildings.
The core is low-alloy high-strength structural steel such as Q235B and Q355B, and form is mostly H-shaped steel, I-shaped steel, steel truss and steel purlin, etc. Its mechanical properties are outstanding, and its tensile and compress strength is much higher than that of concrete, which can support the design of 30-60 meters large span without column, and it can be prefabricated in factory, with a size accuracy of millimeter level, and it is compatible with rapid assembly, which is the guarantee of building structure safety. "Skeleton".

En material: It is mainly color steel plate and insulation sandwich panel, with clear function-oriented. Ordinary industrial factory buildings can choose single-layer color steel plate; cold chain and buildings need to use polyurethane/rock wool sandwich panel; chemical industry and coastal projects are suitable for fluorocarbon coated color steel plate, and can also customize the color match the appearance of the building.

Auxiliary protective materials: including fireproof coatings, anticorrosive coatings, high-strength bolts, etc., are used to solve the pain points of steel structure. Fireproof coatings form an insulation layer at high temperature, which can increase the fire resistance limit of steel members to .5-3 hours; hot-dip galvanizing coating can isolate corrosion and extend the service life of the structure to more than 30 years; high-strength bolts firm connection, suitable for high-rise, vibration load scenarios, and can be dismantled and modified in the later period, to improve the value of building reuse

Advantages of steel structure

The core advantage of the main load-bearing steel such as Q235B, Q355B low-alloy high-strength, with shapes including H-shaped steel, steel truss, etc., lies in its excellent mechanical properties and strong spatial adaptability. Its tensile and compressive strength is higher than concrete, and the section of components can be smaller under the same load-bearing requirements, which can easily achieve a large span of 30-60 meters without, and maximize the release of storage, factory and other spaces; At the same time, it has excellent toughness, and is not easy to brittle under the action of external such as earthquakes and strong winds, and can ensure the stability of the structure for a long time with precise mechanical calculations. In addition, this kind of steel can be prefabric and processed in the factory, with a size accuracy of millimeters, and directly assembled on site, which greatly reduces construction errors and the construction period.

The advantages of steel structure enclosure materials such as color steel plates and insulation sandwich panels are reflected in the flexible switching of functions and outstanding cost performance. The color steel plate is light in weight, quick to install, and can quickly meet the basic needs of rain shelter and wind protection. Moreover, it has rich and customizable colors, to different architectural appearance styles. If insulation and heat insulation are required, EPS and polyurethane core materials can be selected for the sandwich panels, which have a low thermal conductivity can reduce the energy consumption of warehouses and factory buildings by more than 30%. It is perfectly suitable for cold chain and food storage scenarios. Some special enclosure panels can integrate fireproof and corrosion-resistant functions, with a service life of more than 25 years in chemical and high-temperature environments, reducing the cost of later maintenance.

The advantages of auxiliary protective materials for steel structures, such as fireproof coatings, anticorrosive coatings, and high-strength bol connections, lie in their targeted solutions to structural pain points, ensuring long-term safety. Fireproof coatings can form an expansion insulation layer at high temperatures, increasing the fire resistance of steel members to 1.5-3 hours, meeting fire regulations; hot-dip galvanized anticorrosive coatings or fluorocarbon spraying prevent moisture and chemical corrosion, ensuring that even in humid or coastal environments, steel rusting is avoided, extending the structure's lifespan from 15 years to over 3 years; and high-strength bolted connections offer ease of installation and the ability to be disassembled and modified, allowing for warehouse expansions or structural adjustments without the need to the main steel, significantly enhancing the building's secondary utilization value.

What can we offer you

The company typically establishes long-term and stable cooperative relationships with high-quality steel suppliers around the globe, ensuring that the steel used meets international standards Strict control begins with the procurement of raw materials, and each batch of steel is carefully selected, guaranteeing the high quality of the steel. A professional quality inspection team conducts comprehensive inspection of each component, covering aspects such as appearance, internal quality, dimensional accuracy, mechanical properties, and more. Equipped with a professional quality inspection team, strict quality control exercised in every production link to ensure that products meet relevant standards and specifications. It has also obtained multiple certifications such as ISO9001 quality management system certification, further ensuring quality of the steel. Advanced welding technology, cutting processes, and anti-corrosion treatment are used to ensure the quality and service life of the steel structure. Anti-corion treatments such as hot-dip galvanizing are applied to the steel to enhance its ability to resist external environmental erosion and extend the service life of the steel structure.

The company has an experienced professional design team, team members are familiar with various steel structure design specifications and manufacturing processes, and can provide tailored steel solutions according to customer needs and building characteristics. With the help of advanced computer-aided design (CAD) and finite element analysis software, the stress conditions of steel structures are precisely and deeply analyzed. Through simulation, designers can predict the stress distribution and deformation trend of the structure under different working conditions in advance, and then optimize and adjust the design scheme to ensure safety, stability and reliability of the steel structure. The design team is constantly exploring new structural forms and design methods to improve product performance and economy. It can not only design according to or domestic standards to ensure the safety and rationality of the structure, but also provide personalized custom design services according to the special requirements of customers, such as special spatial layout and needs, to meet the diversified needs of different customers.

Professional transportation plan: for different sizes and weights of steel structure components, develop personalized transportation plans. Professional transportation equipment and protective measures are adopted, such as special transportation racks, lashing belts, cushioning materials, etc., to ensure that the components are not damaged during transportation. At the same time, we should reasonably plan transportation routes, optimize transportation plans, reduce transportation costs, and provide customers with efficient and economical transportation services.
