Purchasing Guide

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

  • For procurement requirements that require the use of fiberglass trench cover plates, it is recommended to prioritize specifications with a corrosion resistance level of ≥ 95% and a bearing strength of ≥ 3 tons/㎡ based on actual application scenarios such as chemical parks, sewage treatment plants, and other environments.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure supply stability and long-term cooperation potential.
  • In high-frequency usage scenarios such as municipal drainage or power pipe trenches, attention should be paid to the anti slip pattern design (friction coefficient ≥ 0.6) and flame retardant performance (oxygen index ≥ 28) of the fiberglass trench cover plate to comply with safety regulations.
  • Fiberglass trench cover plates with different thicknesses (usually 25mm-50mm) are suitable for differentiated scenarios such as vehicle passage or pedestrian walkways. When purchasing, parameter comparisons should be made based on load standards and span requirements.
