Hot Dip Galvanized External Wall Insulation Welded Wire Mesh Alkali Resistant for Building Envelope Reinforcement

External Wall Thermal Insulation Welded Wire Mesh is a specialized reinforcement fabric produced by resistance spot welding longitudinal and transverse steel wires at every intersection. The mesh serves as a critical component in external thermal insulation composite systems, providing structural reinforcement that bonds insulation boards with mortar layers while preventing surface cracking. Manufactured with hot-dip galvanized surface treatment, the mesh delivers reliable alkali resistance against cement mortar corrosion and maintains long-term outdoor durability. With uniform flat mesh surface, thin wire diameter, lightweight profile and standardized specifications, it meets the rigorous demands of modern building envelope insulation and anti-crack plastering applications.

• Firm Welding: Longitudinal and transverse wires are formed by resistance spot welding with solid welding points, avoiding cracking and solder detachment during plastering construction.
• Crack Resistance and High Tensile Strength: Strong toughness can effectively disperse mortar stress and prevent hollowing and cracking of external wall insulation and plaster layers.
• Alkali and Corrosion Resistance: Mostly made by hot-dip galvanizing to resist alkaline corrosion of cement mortar, with long service life outdoors.
• Uniform and Flat Mesh: Neat mesh panels fit closely with insulation boards, featuring strong adhesion for mortar plastering.
• Thin and Lightweight Material: Thin wire diameter and light weight will not increase wall load, easy to cut and install.
• Good Air Permeability: The mesh structure helps wall moisture escape and reduces wall dampness, peeling and shedding.
• Standard Specifications: Unified wire diameter, mesh aperture and width, in line with standard external wall insulation construction requirements and available for mass production.

• Building External Wall Insulation: Plastering mesh for EPS boards and XPS boards to reinforce insulation layers.
• Internal Wall Anti-Crack Plastering: Mortar plastering for indoor walls and ceilings to avoid fine cracks and hollowing.
• Roof Insulation Reinforcement: Laid under roof insulation to strengthen the bonding force between mortar and insulation boards.
• Old Building Renovation: Repair old walls and renovate external walls to prevent cracking and shedding of new and old mortar layers.
• Exterior Wall Projects of Villas and Communities: Special wire mesh for commercial buildings and self-built houses.
• Various Cement Components: Built-in anti-crack mesh for flues, cement fences and decorative cement boards.

Each roll or panel is wrapped with moisture-proof protective film to prevent surface treatment damage during transit, then secured on export-grade wooden pallets or packed in reinforced export cartons. All products undergo welding joint tensile testing, mesh uniformity inspection, surface treatment adhesion verification and dimensional accuracy checking before dispatch. Standard delivery within 7-15 working days with flexible payment options for sample orders and bulk purchases.
