Product Description

Welded wire reinforcement (construction mesh) is an efficient and economical replacement for rebar as reinforcement in concrete construction. The use of welded wire reinforcement saves time and installation costs compared to standard rebar concrete reinforcement. Wires are welded into a sheet eliminating the time needed for tying rebar, and ensuring that the wires will not move when concrete is placed.

Application

Welded steel fabric/ mesh has been widely adopted in the construction industry, not only for prefabricated concrete components, but also applied more frequently to cast-in-place concrete structures, such as:

1. Transportation Industry

Highway deck pavement, concrete pavement for soft ground sections, base plates of high-speed rail tracks, surface crack prevention on bridge piers, concrete ground for toll plazas, concrete ground for railway platforms, stations, and cargo areas, concrete ground for airport runways, cargo areas, and parking lots, tunnel lining, etc;

2. Municipal Engineering

Municipal bridge and overpasse's deck pavement, concrete pipe galleries, drainage channels, underground culverts, fences, slope protection, etc;

3. Water Conservancy, Electricity, Mining

Water conservancy facilities, dams, wharfs, ports, electric power engineering foundations, shotcreting and bolting support in mines, etc;
