Purchasing FAQs

Clear answers to help you prepare specifications, compare quotations and plan delivery.

01. What if the catalogue does not include the specification I need?

Yes, we offer OEM guardrail production according to customer drawings. Send your drawings, required standard, material and coating requirements. We will review the details and confirm the production specification and supply scope before quotation.

02. What information do I need for a guardrail quotation?

Please provide the product type, quantity, dimensions, steel grade, coating requirements and destination port. Include project drawings, a bill of quantities (BOQ) and the required standard if available. If some details are not yet decided, we can help clarify the requirements before preparing a quotation.

03. Can you supply matching posts and accessories for my project?

Yes. The supply can include guardrail beams, posts, spacers or blockouts, bolts, washers, nuts and project-specified terminals or transitions. We confirm the bill of materials and the exact supply scope against your drawings before production.

04. Should I choose W-beam or Thrie-beam guardrail?

Follow the project design and approved barrier system. Beam shape alone does not determine protection performance: posts, spacing, connections, terminals and installation conditions also matter. Any change to the specified system should be approved by the project engineer.

05. How do I choose between hot-dip galvanizing and powder coating?

Consider the service environment, required colour and maintenance requirements. Hot-dip galvanizing provides a zinc coating for corrosion protection; powder coating provides a coloured finish. Confirm whether powder coating is applied over galvanized steel and specify the complete coating system in the project requirements.

06. Why do guardrail quotations vary between suppliers?

Compare steel grade, base-metal thickness, coating requirements, dimensions, accessory quantities, packing and delivery scope on the same basis. A lower price may reflect a different specification or an incomplete supply scope. Ask for an itemized quotation against the same drawings and requirements.

07. What inspection or certification documents can I request?

Tell us which documents your project requires before ordering. We will confirm the material, dimensional, coating inspection and traceability records available for the quoted product. A material certificate is not a crash-performance rating; any system test or approval document must match the proposed barrier configuration.

08. How are production lead time and shipping time confirmed?

Timing depends on the confirmed specification, quantity, coating process, production arrangements and destination. Production lead time and shipping transit time are confirmed separately in the quotation or contract. Send your required delivery date so we can review the schedule.

General purchasing guidance. Final specifications must follow approved project drawings and contract requirements.
