With the rapid development of modern industry, the requirements for material properties are increasing day by day. Among numerous materials, hot-dip galvanized aluminum magnesium alloy coated steel strips have been widely used in fields such as construction, transportation, and energy due to their excellent anti-corrosion and mechanical properties. In order to standardize and guide the production and application of this material, the group standard T/SSEA 0346-2024 "Continuously hot-dip galvanized aluminum magnesium alloy coated steel strips for structural use" has emerged.

This standard is under the centralized management of the Group Standards Technical Committee of the China Steel Structure Association, and was jointly drafted by Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. and other units. It specifies the requirements for the designation, classification and code, ordering content, size, shape, weight, technical requirements, test methods, inspection rules, packaging marks, and quality certificates of continuous hot-dip galvanized aluminum magnesium alloy coated steel strips for structural use, providing users with clear procurement basis and acceptance standards.

This document not only ensures the stable and consistent quality and performance of galvanized strip zinc aluminum magnesium products, improves the market competitiveness of the products, but also provides convenience for communication and cooperation between producers and consumers. At the same time, the formulation of this standard also helps to promote the healthy development of the galvanized strip zinc aluminum magnesium industry, and promotes technological progress and innovation in the industry.

Galvanized square square tube with zinc aluminum magnesium strip is cut, rolled, welded, supplemented with zinc, passivated, cut and packaged with low coating zinc aluminum magnesium steel strip as raw material. On the basis of the original galvanized steel strip process, Tianjin Yuantai Derun Group has developed, designed, debugged, and tested steel strips made of aluminum magnesium alloy as raw materials for the production of galvanized strip square rectangular tubes. This product has better corrosion resistance than traditional galvanized strip square rectangular tubes, and has advantages such as high aesthetics and good mechanical properties due to cold rolling and shaping of the raw materials. Widely used in civil construction, transportation, decorative guardrails and other fields.

By implementing the group standard T/SSEA 0346-2024 "Continuous hot-dip galvanized aluminum magnesium alloy coated steel strips for structural use", it helps to improve product quality, regulate market order, promote technological innovation and industrial upgrading, and promote high-quality development of the industry. At the same time, it also provides users with clearer product selection and acceptance criteria, safeguarding their legitimate rights and interests.
