Fiberglass Netting Mesh Complete Guide: Uses & Specs

Understanding Fiberglass Netting Mesh for Construction Applications

Fiberglass netting mesh, also known as fibreglass netting, is a versatile alkali-resistant open-weave fabric made from woven E-glass or C-glass fibers coated with acrylic or AR (alkali-resistant) polymers. This reinforcement material prevents cracking in cementitious systems, distributes stresses uniformly, and enhances tensile strength in plaster, stucco, EIFS (Exterior Insulation Finish Systems), stone veneer, and waterproofing membranes.

Fiberglass netting China manufacturers dominate global production with massive scale—GuangSou company’s 67,000m² facility produces 1.5 million m² daily across 2,600 looms, achieving $70M annual sales across UAE, Saudi Arabia, Central Asia, Russia, and Latin America. Their complete industrial chain (yarn → weaving → coating → finishing) ensures consistent quality from 45g/m² wall plaster mesh to 160g/m² heavy-duty structural reinforcement.
