Standards & Reference Specifications

We work according to project requirements confirmed through quotation, drawings, and technical communication before production.

Common Reference Standards

Common reference standards may include: GB ?? ANSI/NAAMM ?? ASTM ?? EN/BS ?? AS/NZS. Final production requirements are subject to confirmed project specifications and technical review.

GB ANSI/NAAMM ASTM EN/BS AS/NZS

China (GB) standard: As a China-based manufacturer, we support GB (Guóbiāo) and YB/T 4001.1 for steel bar grating. Common GB spacing: W255/30/100, W323/40/50. US (ANSI/NAAMM): 19-W-4, 15-W-2. Specify your target standard in the RFQ.

Manufacturing Control

Practical controls aligned to specification before production and shipment.

  • Raw material verification
  • Fabrication and fit-up control
  • Dimensional inspection
  • Finish verification
  • Packing inspection

Documentation Support

Include required standards and documents in your RFQ so we can confirm scope before order. Traceable production documentation available on request.

QA / inspection points

Typical checkpoints for consistent fit, finish, and shipment readiness.

Stage Checkpoint
Material Material identification and basic verification per order requirements.
Fabrication Fit-up and workmanship inspection before finishing.
Dimensions Length/width/diagonal checks and tolerance confirmation as quoted.
Finish Visual finish check and consistency confirmation per quotation.
Packing Packing condition and labeling for sea freight shipment.

FAQ

Short answers for common engineering and procurement questions.

Which standard should I specify?

Use your project requirement. If unsure, share application, load, and region—we'll suggest a reference for quotation.

Can you quote to project-specific requirements?

Yes—provide drawings, tolerances, finish, and documentation needs so scope is clear before production.

What galvanizing standard can be referenced?

We confirm finish requirements in quotation. Provide target references if your project mandates them.

Can test reports or certificates be provided?

Available on request where applicable. Include your documentation needs in the RFQ.

How are dimensional tolerances controlled?

We perform dimensional checks per order requirements and confirm tolerances as quoted.

Need documentation support for your project?

Send requirements and drawings. We'll confirm standards and scope for quotation.
