Product Overview

Our Welded Mesh For Construction is engineered from high-tensile HPB300 (smooth) or HRB400 / HRB500 (ribbed) grade steel bars to deliver superior yield strength and exceptional bonding capacity in structural elements.

Manufactured for heavy industrial use, it is the premier choice for global importers and construction wholesalers supplying foundations, precast panels, and roadway projects.

Product Parameters

Material	HPB300 (Smooth) / HRB400 & HRB500 (Hot-Rolled Ribbed)
Mesh	5×5cm ~ 10×20cm, customization available.
Size	1×2m, 1×3m, 2×3m, etc., customization available.
Wire Diameter	1.5mm to 10mm; the thicker the wire, the better the load-bearing capacity.
Welding Process	Resistance welding: The shear strength of the weld joint is ≥ 0.3 times the tensile strength of the steel wire.
Surface Treatment	Black steel wire (can be galvanized or epoxy coated) Galvanized layer thickness ≥40μm (optional)
Implementation Standards	Chinese National Standard GB/T 1499.3 / British Standard BS 4483 / American Standard ASTM A1064

Technical Advantages

Features a hot-rolled ribbed profile on HRB grades that substantially increases mechanical interlocking with concrete to minimize structural micro-cracking.

Processed via microcomputer-controlled CNC resistance welding to deliver uniform weld-shear strength that prevents joint separation under onsite heavy machinery and labor tracking.

Manufactured using integrated online straightening systems so each sheet lies flat, reducing onsite contractor installation and alignment times by up to 30%.

Packed in heavy-duty secured bundles fitted with reinforced steel lifting loops to facilitate safer and faster forklift or crane unloading at destination warehouses.

Customization & OEM Capabilities

Fully support custom fabrication based on your local market standards (e.g., specific wire gauge combinations, non-standard mesh apertures, and tailored overhang/flying ends).

Offering flexible options for customized sheet branding, bundled labeling, and mixed-specification container loading to support your distribution networks.

Project Reference & Application Scope

HRB400 / HRB500 Ribbed Mesh: Optimized for heavy-load structural elements including industrial floor slabs, raft foundations, precast concrete walls, and bridge decks.

HPB300 Smooth Mesh: Primarily applied in light-load concrete pavement, residential driveways, precast boundary walls, and shotcrete retaining structures.

Quality Control & Inspection

We conduct rigorous in-house testing for every production batch before loading:

Dimensional Inspection

Wire diameter, sheet size, and mesh spacing tolerance control.

Tensile & Elongation Testing

Verifying HPB300/HRB400/HRB500 yield strength.

Weld-Shear Test

Ensuring joint strength meets the ≥0.3 tensile strength threshold.

Third-Party Inspection

Fully support SGS, BV, or Intertek inspections based on client requests.

FAQ

Q: Do your steel meshes comply with our local building codes?

A: Yes. We manufacture strictly to ASTM A1064, BS 4483, or AS/NZS 4671 standards, and provide a traceable Mill Test Certificate (MTC) with every shipment to guarantee fast local compliance approval.

Q: How do you ensure the weld joints won't break during handling?

A: Our automated CNC resistance welding ensures deep fusion at every intersection, delivering a weld-shear strength that easily withstands heavy onsite labor and machinery tracking.

Q: Can you manufacture custom sizes or configurations?

A: Yes. We provide full OEM customization for wire diameters, non-standard mesh apertures, unique sheet dimensions, and specific flying ends to match your market needs.

Q: What is your standard lead time and sample policy?

A: Production takes 15–20 days. We offer complimentary mesh samples so you can conduct independent tensile, bending, and weld-shear testing before ordering.

Q: Are the bundles designed for easy unloading at our local warehouse?

A: Yes. Every bundle is limited to 2 to 2.5 Metric Tons and configured with extended, heavy-duty steel wire lifting loops. This allows your crane or forklift operators to safely unload a 20ft container in under 30 minutes.
