Product details
Cost Savings Through Higher Strength:Our high-strength rebar (e.g., CRB600H, 430MPa vs. HRB400's 360MPa) reduces theoretical steel consumption by over 16% for the same load requirements, directly lowering material and shipping costs.
Superior Seismic Safety:Excellent ductility and high elongation allow the rebar to absorb energy during earthquakes, preventing sudden brittle failure and providing reliable structural protection when it matters most.
Faster Construction
Green & Policy-Compliant:High-strength rebar reduces resource use and carbon emissions-CRB600H is listed 's national "Encouraged Category," helping your project meet green building standards and stay ahead of regulations.

Frequently asked questions
Genuine GB rebar has the grade mark and "GB" symbol rolled onto the surface, with a matching tag and mill certificate for each bundle. Use a caliper to measure the inner diameter - a nominal 10mm bar measuring ~8.8mm indicates "shrunk" rebar. Weight deviation testing is mandatory per GB standards, and non-compliant products are prohibited from use. Always verify the three-way match: tag, surface markings, and certificate.
Four checks are mandatory: verify documentation (mill certificate, quality certificate) for matching grade/batch; conduct visual inspection for cracks, oil stains, and excessive rust; perform on-site diameter measurement; and arrange witnessed lab testing - with a maximum of 60 tons per batch for yield strength, tensile strength, elongation, bending, and weight deviation. Seismic grades (suffix "E") require additional tensile/yield ratio tests.
HRB400 (400MPa) is the standard choice for general structures; HRB500 (500MPa) suits high-rise and large-span projects; CRB600H (574MPa, 430MPa design value) offers 16.3% theoretical steel savings over HRB400 and is listed 's national "Encouraged Category" - making it the most economical option when combining material and shipping costs.
Three critical indicators must be met: tensile/yield strength ratio ≥ 1.25, yield ratio ≤ 1.30, and total elongation at maximum force ≥ 9%. Failure on any parameter means the rebar cannot provide reliable seismic protection and should be rejected.
Factory-fabricated to precise specifications, welded wire mesh eliminates on-site spacing errors and missed ties while reducing installation time by up to 54%. This translates to shorter schedules, lower labor costs, and consistent quality - ideal for floor slabs, wall panels, and prefabricated construction.
Theoretical weight (kg/m) = Diameter(mm) * Diameter(mm) * 0.00617. A minimum of five samples per batch are tested; if actual weight falls below theoretical weight beyond GB-standard limits (GB 1499.2 or GB 13788), the batch is rejected. A simple weigh-check upon arrival serves as an effective first-line defense against non-standard rebar.
Construction rebar requires production license numbers formatted as XK05-001-***** or XK05-002-*****, verifiable online via the National Industrial Product Production License Public Inquiry System. Note: as of September 25, 2024, cold-rolled ribbed rebar is newly added to the license catalog. Always perform a three-way match: tag, surface markings, and mill certificate must align.
Key issues include: hook non-compliance (straight length < 10d or angle < 135°); rib damage from over-tight straightening machines; insufficient or missed ties; inadequate concrete cover leading to exposed rebar; and over-long exposed threads in mechanical connections. Solutions: calibrate bending machines, adjust straightening rollers, use "figure-eight" tying patterns, install sufficient spacers, and use torque wrenches for threaded connections - with rebar inspection mandatory before concrete
