Purchasing Guide

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

  • For procurement requirements that require the use of glass magnesium board, it is recommended to prioritize confirming key technical parameters such as thickness (8-20mm), fire rating (Class A), and density (1.0-1.3g/cm ³) to ensure compatibility with engineering requirements.
  • In high-frequency application scenarios such as industrial plant partitions and ship bulkheads, attention should be paid to the impact resistance and moisture resistance of glass magnesium sheets to avoid deformation or strength reduction caused by environmental factors.
  • 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 reduce procurement risks.
  • When using glass magnesium board as a fireproof partition material, it is recommended to evaluate the stability and compliance of the supplier's products based on combustion performance testing reports and actual cases.
