Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of steel structures, it is recommended to select corresponding specifications based on key technical parameters such as project span and load-bearing capacity. There are significant differences in the requirements for cross-sectional dimensions and yield strength between industrial plants and high-rise buildings.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, suppliers who have been involved in large-scale infrastructure projects for a long time are usually more familiar with material standards under complex working conditions.
  • In large space scenarios such as warehousing and logistics facilities, it is recommended to pay attention to the anti-corrosion coating performance and seismic design parameters of steel structures. Such scenarios require high durability and dynamic load adaptability of materials.
  • When purchasing from different climate regions, attention should be paid to the low-temperature toughness or weather resistance indicators of steel. There are differentiated requirements for material certification standards for steel structures in northern cold regions and coastal high humidity environments.
