TL;DR
Welded reinforcing mesh must match the standard named in your project specification. The three grade families buyers request most for export projects are AS/NZS 4671 (500L/500N/500E), BS 4483 (B500A/B/C) and SS 561 (500A/B/C). All sit in the 500 MPa class, but minimum elongation (Agt) ranges from 1.5% to 10.0%. Choose by ductility first, then confirm sheet size, surface treatment and test documents.
Importers in Australia, the United Kingdom and Southeast Asia usually buy welded reinforcing mesh against a named standard, not a generic description. A sheet with the wrong grade designation can be questioned at site inspection, even when the wire looks identical.
The 2026 trade context adds pressure. The EU Carbon Border Adjustment Mechanism (CBAM) entered its definitive period on 1 January 2026, so European importers of steel goods now have to check their obligations more carefully.
This guide compares three grade families using the technical table published on the Tianjin Anguyuan reinforcing mesh page, so you can shortlist a grade before requesting a quotation.
Reinforcing Mesh Standards Compared: Yield, Ductility and Shear
The table lists the minimum values shown on Anguyuan's specification sheet. Rm/Re is the tensile-to-yield ratio; Agt is total elongation at maximum force. Each standard lists a bend test of D = 4d.

- ✦ Highest ductility class: AS/NZS 4671 500E lists Agt of at least 10.0%.
- ✦ Matching top grades: BS 4483 B500C and SS 561 500C both list Agt of at least 6.0% and Rm/Re of at least 1.13.
- ✦ Shear check: BS 4483 lists ≥125×Smax, while AS/NZS 4671 and SS 561 list ≥250×Smax.
Why Ribbed Welded Reinforcing Mesh Suits Slabs and Precast Panels
Anguyuan's reinforcing mesh is also called welded reinforcing rib mesh. The ribbed profile improves bonding to concrete and helps limit cracks caused by concrete shrinkage.
Typical uses include concrete footpaths, industrial and commercial ground slabs, precast panel construction, residential slabs and footings.
Factory welding keeps bar spacing accurate, and the sheet is one piece, so site crews cannot widen the spacing to save time.
Cold-rolled low-carbon wire normally reaches 500 MPa. Compared with tying loose rebar, mesh saves marking, cutting and tying labour, and it reduces on-site cutting noise and safety risk. For complex layouts, see cut and bent fabric.

✦ 500 MPa Class Strength Cold-rolled low-carbon wire normally reaches 500 MPa. |
✦ Less Site Labour No on-site marking, cutting and tying of loose rebar. |
How to Choose Welded Reinforcing Mesh in 5 Steps
|
1Read the specification. Note the exact standard and grade, for example AS/NZS 4671 500N or BS 4483 B500B. |
|
2Keep the ductility class. Do not swap to a lower Agt class unless the project engineer approves it in writing. |
|
3Define the geometry. Confirm wire diameter, mesh spacing and sheet size, because these drive both weight and price. |
|
4Choose the fabric type. Standard sheets suit repeat layouts; purpose-made steel fabric or cut and bent fabric reduces site cutting. |
|
5Request test results. Ask for yield, tensile, Rm/Re, Agt, shear and bend-test data that match your grade before shipment. |
Why Importers Source Reinforcing Mesh from Tianjin Anguyuan
Tianjin Anguyuan Metal Products Co., Ltd. was established in October 2007 and is based in Beichen District, Tianjin. Annual output capacity for welded steel mesh is 30,000 tons.
Products are supplied across China and exported to Europe, Australia, Southeast Asia and other regions. See the equipment and process page for the production line.
According to the application list on the product page, welded steel fabric is used in highway deck pavement, tunnel lining, airport ground slabs, drainage channels and prefabricated buildings.
Material specifications are customised to customer requirements, so buyers can match wire size, mesh spacing and grade to the project drawings. Browse welded steel fabric for options.

Reinforcing Mesh Standards FAQ
What is the difference between AS/NZS 4671 500L, 500N and 500E reinforcing mesh?
-
All three list a minimum yield of 500 MPa. They differ in ductility: 500L requires Agt of at least 1.5% and Rm/Re of 1.03, 500N requires 5.0% and 1.08, and 500E requires 10.0% with Rm/Re between 1.15 and 1.4. Use the class your engineer specified.
Which BS 4483 grade has the highest minimum elongation?
-
B500C. It lists Agt of at least 6.0% and an Rm/Re ratio of at least 1.13, compared with 4.0% for B500B and 2.5% for B500A. Anguyuan's table shows a minimum yield of 485 MPa for all three BS 4483 grades.
Which national standards can Tianjin Anguyuan weld reinforcing mesh to?
-
The company states that it produces welded mesh to China's GB/T 1499.3-2010, Australia's AS/NZS 4671:2001, the UK's BS 4483, Germany's DIN 488, Switzerland's SIA 16211 S 550 and France's NF A35-016.
What determines the price of welded reinforcing mesh?
-
Specifications are customised, and raw material prices fluctuate. The final price depends on wire thickness, mesh size, sheet size and surface treatment, so send your drawings or bar schedule to receive an accurate quotation.
Does EU CBAM apply to welded reinforcing mesh in 2026?
-
CBAM entered its definitive period on 1 January 2026, and EU importers above 50 tonnes per year need authorised declarant status. Scope follows the CN code on the customs declaration. The Commission proposed extending CBAM to more downstream steel goods in December 2025, so confirm your mesh's CN code and the current rules with a customs broker.
Choosing between 500L, 500N, B500B or SS 561 grades is simpler once the specification is on the table. Send your project standard, wire diameter and sheet size, and the Anguyuan team can confirm which grade and fabric type fits your reinforcing mesh order.
