Tianjin Yuantai Derun offers galvanized square pipe spot processing services
Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd., a large-scale square and rectangular pipe production base in North China, provides comprehensive galvanized square pipe spot processing services, covering the entire process from spot inventory, custom processing, and quality assurance. The following is a detailed analysis of its services:
1. In-Stock Inventory and Specification Advantages
Extensive Inventory, Comprehensive Specifications
Inventory: Over 200,000 tons of black square and rectangular tubing, hot-dip galvanized square and rectangular tubing, zinc-aluminum-magnesium square tubing, and other products are always in stock, meeting large-scale procurement needs.
Specification Range: Supports square tubing sizes from 20×20mm to 1000×1000mm, with wall thicknesses from 0.5mm to 50mm, and materials ranging from Q195 to Q460, offering nearly 9,000 specifications.
Flexible Customization: Custom-to-length production is available, with a minimum guaranteed length accuracy of ±2mm, meeting individual project requirements.
Diverse Galvanizing Options
Blowing Process: Average zinc coating of 30μm (426g on both sides), suitable for general corrosion protection applications.
Rack Plating: Average zinc coating of 60μm, with a maximum guaranteed coating of 100μm, offering excellent corrosion resistance and suitable for harsh environments.
II. Processing Capabilities and Technical Strength
Full-Chain Processing Services
Cutting/Drilling: Precision cutting, supporting special-shaped holes to meet pipe connection requirements.
Bending/Welding: Equipped with cold-bending steel units, we can achieve complex bending shapes. Professional welding services are provided to ensure structural strength.
Customized Galvanizing: We adjust the galvanizing thickness based on the operating environment, balancing cost and corrosion resistance.
Advanced Equipment Ensures Precision
Production Lines: We have 10 hot-dip galvanizing lines and a 600x600 large-section square and rectangular pipe production line, with a daily output of 5,000 tons.
Processing Equipment: Equipped with bending, straightening, and cutting equipment, we ensure processing accuracy and efficiency, with a particular focus on processing large-diameter, thick-walled square and rectangular pipes.
III. Quality Assurance and Testing Standards
Strict Quality Control of the Galvanized Coating
Uniformity Test: No red metallic copper deposits were observed after five consecutive immersions in a copper sulfate solution, confirming no missing coatings.
Adhesion Verification: After a cold bend test (90° bending angle, radius 8 times the pipe diameter), the coating showed no peeling or cracking.
High-Standard Testing
National Standards: Strictly adhere to GB/T6728-2017, "Cold-Formed Hollow Steel Sections for Structural Use," to ensure product compliance.
Company Standards: Implementation of Group Standard T/CSCS TC02-04-2018. Galvanized coating thickness and uniformity exceed national standards.
Certification System: ISO9001 certified. Our products are widely used in construction, machinery, power generation, and other fields, and have an excellent reputation.
