We rely on the AISC American standard specifications to provide full-chain customized processing for the W36 series heavy-duty wide-flange W-shaped steel. This meets the differentiated requirements of overseas steel structure projects. The entire process is as follows:
1. Precise cutting and trimming: Based on the drawing dimensions, use CNC flame / plasma cutting equipment to cut the W36 steel to the specified length. Strictly control the straightness of the cut edges, remove the chips and burrs, ensuring the accuracy of the subsequent assembly, and avoiding errors in the assembly of heavy components.
2. Cold bending processing: Carry out arc-shaped and inclined curved arc forming as needed. For W36 large-section heavy steel beams, use dedicated steel bending fixtures to control the rebound amount, ensuring the arc curvature and chord length conform to the drawings, and used for arc-shaped beams and arch frame special structures.
3. Professional welding forming: Use welding processes suitable for American standard structural components to weld the W36 steel joints and node plates. Perform preheating before welding and post-weld inspection. The weld seams meet the AISC structural welding acceptance standards, ensuring the structural stability under heavy-load conditions.
4. Numerical control drilling and hole making: Use a CNC drilling machine to batch process bolt holes and positioning holes. The hole positions, diameters, and spacings strictly match the North American steel structure connection node drawings. The hole walls are smooth, suitable for high-strength bolt assembly.
5. Surface protection treatment: According to project requirements, carry out sandblasting rust removal, primer, intermediate paint, and topcoat coating. We can also provide anti-corrosion solutions such as hot-dip galvanizing as needed. Remove surface oxide scale to enhance the durability of W36 steel in outdoor, humid, and corrosive conditions.
6. Component pre-assembly inspection: Complete overall pre-assembly in the factory. Verify the dimensions, joint gaps, and alignment of the components, and identify potential assembly interference issues in advance. Issue size inspection records, and pack and ship them overseas to reduce the difficulty of on-site installation.

1. Super high-rise building frame load-bearing main beams: The W36 steel section has strong bending resistance. As the main load-bearing component of the high-rise steel frame, it bears vertical loads and lateral wind pressure, ensuring the overall stiffness of the building.
2. Large-span factory roof beams: Suitable for large-span industrial plants, reducing the layout of intermediate columns and releasing internal usage space, meeting the load requirements of heavy production workshops.
3. Main beams and bridge piers caps of highways and railways: Can be used as the main load-bearing steel beams of the bridge, bearing vehicle dynamic loads, suitable for municipal and transportation infrastructure projects, and meeting the acceptance requirements of American standard engineering.
4. Heavy-duty metallurgical equipment support bases: Used as the supporting base for large metallurgical machinery such as continuous casting machines, rough rolling machines, and tunnel furnaces, bearing the self-weight of the equipment and production impact loads.
1.Precise Matching of American Standard System
The entire W36 series strictly adheres to the AISC and ASTM A992/A572 Gr50 standards. The cross-sectional parameters, tolerances, and North American engineering drawings are fully aligned. It supports stable supply of multiple specifications such as W36×135, W36×231, W36×247, and W36×262, and can directly meet the review requirements of American infrastructure, bridges, and super-tall projects.
2. Integrated Processing Capability for Heavy Components
For the complete processing services of W36 large-section heavy steel beams, it includes CNC cutting, arc bending, welding, hole making, anti-corrosion coating, and on-site pre-assembly. There is no need for customers to find separate processing factories, reducing errors in multiple connections, and it is suitable for complex heavy-load steel structure nodes.
3. Delivery Solution for American Projects
Familiar with the inspection requirements, packaging norms, and shipping procedures for American standard projects, it can provide material certificates, test reports, support for batch production as per customer's needs, and reasonable packaging and fixation of long materials to reduce the risk of deformation during ocean transportation, and is suitable for various trade terms such as FOB and CIF.
4. Engineering Support and Technical Services
It has a technical team familiar with North American steel structures. It can assist in verifying cross-sectional parameters and processing drawings, provide selection suggestions for scenarios such as roads and bridges, heavy equipment bases, and super-tall frames, respond quickly to project changes, and solve technical questions on-site for customers.
Protection method: The components are placed layer by layer, with rubber buffer pads laid between each layer to isolate the flange and web plates, avoiding friction and scratches during transportation. Protective corner guards are added at the edges.
Binding and fixation: A steel frame is used for positioning, and high-strength steel cables are combined with anti-slip clips for multi-point fastening. The binding position is avoided from the stressed areas to prevent sliding during ocean transportation.
Identification documents: Waterproof labels are used to mark the specifications, materials, furnace batch number, and project number. The material certificate and inspection documents are provided along with the goods, facilitating overseas counting and acceptance.
Shipping plan: Short-sized items are loaded into container trucks, while extremely long steel beams are transported by bulk carriers. During loading, the center of gravity is controlled, and anti-toppling reinforcement is done to ensure the safety of ocean transportation.
