Steel Structure Sections
Standard sections are those described in published standards worldwide and there are also specialized/proprietary sections.
I‐beams (capital “I” sections — in the UK this includes universal beams (UB) and universal columns (UC); in Europe, this includes IPE, HE, HL, HD and more sections; in the US this includes wide flange (WF or W-shape) and H-shape sections)
Z-beams ( reverse half-flanges)
HSS (Hollow Structural Sections, also known as SHS(Structural Hollow Section); includes Square, Rectangular, Circular (Tubular) and Oval Sections) .
Angles (Section in shape of L)
Structural channels, C channel, or "C" sections
T Beams (T Shaped Sections) .
Bars are rectangular in cross-section, but are not wide enough to be defined as plate.
Rods are round or square sections with a length that is long relative to its width.
Plates are sheet metal that is more than 6 mm or 1⁄4 inch thick.
Steel structures are structures in which steel is used as the main load bearing element. And due to the high strength, light weight, fast construction and good seismic performance of steel structure, it has been widely applied in many fields. Its key areas of application are:
Civil Engineering
1. Industrial Buildings - Factories: machining, metallurgy, chemical plants and so on.
2. Warehouses: Large logistics and storage centers(such as high-bay warehouses and cold chain warehouses);
3. Civil Buildings - High-rise Buildings: Main frame of super-high-rise buildings ( e.g. skyscrapers) ;
4.Public Buildings: Stadiums, exhibition halls, theaters, airport terminals and so on.
5. Residential Buildings: Residential building with steel structure are applicable.
Transportation Infrastructure
1. Bridge Engineering - Long-span bridges - Railway/highway bridges
2. Rail Transit and Stations - High-speed rail stations, subway station concourses - Rail transit vehicles
Special Engineering and Equipment
1. Marine Engineering - Offshore Platforms: Main structures of oil drilling platforms (jacket, platform decks);Shipbuilding
2. Hoisting and construction machinery - Cranes - Special vehicles
3. Large Items and Containers - Industrial storage tanks - Mechanical equipment frames
Other Special Scenarios
1. Temporary buildings: disaster relief housing, temporary exhibition halls, prefabricated buildings, etc.
2. Glass dome supports for large shopping malls
3. Energy/business engineering – wind turbine towers (rolled high-strength steel plates) and solar panels.
Cutting Process
1. Preliminary Preparation
Material Inspection
Drawing Interpretation
2. Choosing the Appropriate Cutting Method
Flame Cutting: Suitable for thicker mild steel and low-alloy steel, ideal for rough machining.
Water Jet Cutting: Suitable for a variety of materials, especially heat-sensitive steel or high-precision, special-shaped parts.
Welding Processing
Our welding processing services include cutting, welding, assembly, and fabrication of structural steel components according to customer drawings and project requirements. Using advanced equipment and skilled technicians, we ensure precise dimensions, strong welds, and high-quality finished products for construction, industrial, and infrastructure applications.
Based on the construction drawings or welding procedure qualification report (PQR), clearly define the weld joint type, groove dimensions, weld dimensions, welding position, and quality grade.
Punching Processing
Our punching processing service provides precise hole fabrication for a wide range of structural steel components, ensuring high dimensional accuracy, clean hole edges, and consistent quality. Using advanced CNC punching equipment, we can process various hole diameters, shapes, and layouts according to customer drawings or project specifications.
Our punching capabilities are suitable for H beams, I beams, channels, angles, steel plates, square tubes, rectangular tubes, and other structural steel products. The process improves assembly efficiency, reduces on-site fabrication time, and ensures accurate alignment for bolted connections.
According to the construction drawings, state the hole position (coordinate dimensions), quantity, diameter, the amount of accuracy (e.g., ±1mm tolerance for common bolt holes, ±0.5mm tolerances for high-strength bolt holes) and hole type (round, oblong, etc.). Make hole location marks on the surface of the part with a marking instrument (steel tape measure, stylus, square or sample punch). Use a sample punch to make locating points for critical holes to help guarantee accurate drill locations.
Surface treatment is an essential process for improving the durability, corrosion resistance, and appearance of structural steel products. We provide professional surface treatment solutions according to different project environments and customer requirements.
Main Surface Treatment Options:
1. Hot Dip Galvanizing (HDG)
Provides a durable zinc coating that offers excellent corrosion protection and long service life. Suitable for outdoor structures, bridges, industrial buildings, and harsh environments.
2. Painting / Coating Treatment
Includes epoxy coating, polyurethane coating, and anti-corrosion paint systems. Available in different colors and coating thicknesses to meet specific protection requirements.
3. Shot Blasting
Removes rust, scale, and surface impurities to improve coating adhesion and prepare steel surfaces for painting or further processing.
4. Powder Coating
Provides a smooth and attractive finish with good resistance to corrosion, weathering, and abrasion, commonly used for architectural steel components.
5. Electro Galvanizing
Creates a uniform zinc coating with a clean surface finish, suitable for applications requiring moderate corrosion protection and appearance quality.

Under the constraint of structural security, material consumption is reduced and the construction procedures are simplified. We offer full follow up package services including delivery of drawings to technical briefing on site. Our expertise guarantees the smooth execution of every steel building project, making us a reliable, single-source design ally.
The packaging of steel products should be classified according to the component, size, distance of transit, storage environment and protection level. It is the aim not to get any deformation, rust or damage in the transportation and storage.
The following is the packaging method of steel structure:
1. Bare Packaging(Un-packaged)
For: Large and heavy steel parts(like steel columns, beams, large trusses).
Features:Forget about any extra packaging layer, you can load and unload with lifting tools, directly. But components need to be firmly tied down in transport to avoid rattling/impacting.
Extra Protection: you can provide temporary covers or wrapping component connections (bolt holes, flange surface) to prevent intrusion and damage.
2. Bundled Packaging
Suitable for: Small medium regular shaped steel pieces (like angle steel, channel steel, steel pipes and small connecting plates) in bulk.
Note: The bundling should not be too tight. the bundling is too loose and the elements will shift, if too tight it may cause deformation.
3. Wooden Box/Wooden Frame Packaging
Applicable Scenarios: small precision steel parts (mechanical parts: high precision connectors, etc.), fragile parts (such as small parts like bolts and nuts) or steel parts needing long distance transportation or export.
Benefits: Great protection, isolation from the environment, environmental shielding, protection from long distance transportation in complex environment.
4. Unique Protection Packaging
For Anti-corrosion: When storing steel parts or in humid environment for transportation of steel parts, additional anti-rust processing is required other than above wrapping methods.
For Deformation Protection: When packing slender and thin wall steel (e.g. slender steel beam, thin walled steel member), use additional supports (wood or steel brackets) as packing material, to avoid the packing bending and deform by uneven weight during transportation and storage.
Transportation: Express (Sample Delivery), Air, Rail, Land, Train, Sea shipping (FCL or LCL or Bulk)
