Common steel grades used for industrial catwalks include ASTM A36, ASTM A572, and ASTM A992. These materials offer excellent strength, durability, and corrosion resistance.
Fabrication Process
The following is the step-by-step guide to the steel fabrication process for catwalks:
Step 1: Material Preparation
Steel plates or beams are received and inspected for quality and compliance with specifications. Any surface imperfections or contaminants are addressed through cleaning, grinding, or other appropriate methods.
Step 2: Cutting
Materials are cut to the required dimensions using sawing, shearing, or thermal methods like plasma cutting. In addition, computer numerical control (CNC) machines are often utilized for precise and efficient cutting.
Step 3: Shaping and Forming
This involves processes such as bending, rolling, punching, and drilling. CNC machines are also employed to ensure accuracy and consistency in shaping the steel pieces.
Step 4: Welding and Assembly
The steel components are joined together through welding techniques such as arc welding, MIG welding, or TIG welding. Skilled welders carefully follow the design specifications to ensure strong and reliable connections. Once the welding is complete, the catwalk components — including handrails, guardrails, and any other necessary structural elements — are assembled.
Step 5: Surface Treatment
This typically involves sandblasting to remove surface contaminants, priming, and painting to protect against corrosion and enhance aesthetics. Powder coating is another popular option for surface finishing.
Step 6: Quality Control
Inspections and tests are conducted at various stages, including material receiving, welding, dimensional accuracy, and surface finishing. These inspections help identify defects or deviations from specifications, enabling corrective measures to be taken promptly.
Installation and Maintenance
Professional installers assemble and secure the catwalk following the design specifications and safety guidelines. Proper installation techniques and appropriate fasteners are crucial to ensure stability and safety.
Further, regular maintenance is essential to keep the catwalk in optimal condition. Routine inspections, cleaning, and repairs should be conducted to identify any structural issues, such as corrosion or loose connections, and address them promptly. This proactive approach helps prolong the catwalk’s lifespan and ensures ongoing safety for workers.
