1. Product Overview
Welded rebar mesh, also known as welded steel reinforcement mesh, is manufactured by fully automatic digital high-frequency resistance welding production lines. It mainly includes three mainstream types: cold drawn plain welded mesh, CRB550 cold rolled ribbed welded mesh, and HRB400 hot rolled ribbed welded mesh.
All longitudinal and transverse steel bar intersections are precisely spot-welded, featuring uniform grid spacing, high flatness and strong shear resistance of welding joints. It can completely replace manually bound steel bars on construction sites, serving as standardized building materials for crack resistance and structural reinforcement in residential construction, municipal roads & bridges, water conservancy projects and prefabricated buildings.
We can customize wire diameter, grid spacing, mesh panel length and width as required, with surface treatments including anti-rust oil coating, electro-galvanizing and hot-dip galvanizing. Our products comply with Chinese, American, European, Japanese and other international standards. Each batch can be supplied with mill test certificates and third-party SGS mechanical inspection reports, meeting the requirements of project acceptance and export customs clearance worldwide.

3. Core Product Advantages
1. Greatly Improved Construction Efficiency
Factory prefabricated mesh panels can be laid directly on site, eliminating the procedures of steel bar cutting and manual binding. The laying efficiency is increased by more than 60% compared with traditional binding construction, which significantly saves labor costs and shortens the project construction cycle.
2. Strong Structural Stability & Effective Crack Control
Precision mechanical welding ensures uniform grid layout and balanced force transmission. Ribbed steel bars form mechanical occlusion with concrete for stronger anchoring force, which can effectively control shrinkage cracks of floors, pavements and ground slabs and extend the service life of building structures.
3. High Product Precision & High Project Acceptance Pass Rate
Produced by automatic equipment with small dimensional error and neat flat mesh surface, avoiding irregular spacing and steel bar displacement caused by manual binding, realizing one-time pass of structural acceptance.
4. Diversified Anti-corrosion Solutions for Complex Working Conditions
Anti-rust black steel mesh is suitable for indoor residential construction; hot-dip galvanized rebar mesh can be adopted for riverside, coastal salt-fog and humid environments, which resists acid, alkali and salt spray corrosion and avoids rust for long-term outdoor service.
5. Customized Service & Stable Spot Delivery
We keep tens of thousands of tons of standard specification products in stock all year round, supporting container shipment within 3–7 days. Custom-sized and special-cut mesh panels are available according to construction drawings, together with complete export documents and engineering inspection reports to support long-term bulk overseas cooperation orders.
4. Main Application Scenarios
1. Civil Construction Projects: Anti-crack reinforcement for floors, basement ground, roofs, walls, balconies and parking lots of high-rise residential buildings.
2. Municipal Transportation Infrastructure: Pavement reinforcement for highways, bridge decks, tunnel linings, airport runways and sidewalks.
3. Prefabricated Construction Industry: Internal reinforcement for prefabricated wall panels, laminated slabs, precast stairs and utility tunnel components.
4. Water Conservancy & Port Projects: Anti-crack reinforcement for river slope protection, dam anti-seepage layers, wharf platforms and sewage treatment tanks.
5. Industrial & Municipal Facilities: Ground reinforcement for factory workshops, parking lots, slope protection and bridge crash barriers.
5. Typical Project Cases
1. Domestic High-rise Residential Project
For the floor reinforcement project of multiple high-rise residential phases undertaken by a local urban construction group, Φ6mm @150×150mm CRB550 cold rolled ribbed welded mesh was purchased in bulk. Standard panels realized fast on-site laying, reducing concrete floor cracking rate by 82% and passing structural acceptance at one time. Labor costs and construction cycle were greatly saved, and we became the long-term designated supplier for the residential projects.
2. Overseas Highway & Bridge Project in Malaysia
A local infrastructure company adopted Φ10mm HRB400 hot rolled welded mesh with hot-dip galvanized anti-corrosion treatment for highway bridge deck reinforcement to cope with coastal high temperature and heavy salt-fog environments. No penetrating pavement cracks have occurred after years of vehicle operation, cutting annual road maintenance costs by 75%.
3. Supporting Project for Domestic Prefabricated Component Factory
We supplied custom-sized welded mesh for many domestic prefabricated wall panel and laminated slab manufacturers, which perfectly matched mold dimensions and eliminated steel processing procedures in workshops. The reject rate of precast components was significantly reduced, supporting large-scale mass production of factories.
