Fiberglass Props and Metal Beams
Fiberglass props provide a non-metallic option for specific temporary support applications. Metal roof beams work with props to distribute load. The support plan and mine rules should confirm where each product can be used.

Roof Support Quote Inputs
These values let the technical team narrow the correct prop and beam configuration.
| Input | What to provide | Why it matters |
|---|---|---|
| Working height | Minimum, normal, and maximum support height | Defines model height range |
| Support resistance | Required rated and initial resistance | Matches ground-control design |
| Roof and floor | Strata description and floor bearing condition | Affects base and support selection |
| Support pattern | Spacing, beam arrangement, and quantity | Defines complete system quantity |
| Documents | Required certificate or local approval | Confirms exact model eligibility |
Frequently Asked Questions
Short answers to the commercial and technical questions buyers usually ask before they compare suppliers.
Can you provide an MA certificate for every model?
Document status is checked against the exact model before quotation. Similar product names can have different certificate scopes and validity dates, so we confirm the model, certificate number, holder, and current status as one package.
What information is needed for a technical quote?
Send the model or equipment type, mine conditions, rail gauge or roadway size, voltage, required capacity, quantity, destination, and required document set. Photos, drawings, and an existing equipment nameplate are useful for replacement orders.
Can equipment be inspected before shipment?
Yes. The inspection plan can cover dimensions, nameplates, welds, operating functions, order configuration, document matching, packing, and loading evidence. Test items depend on the equipment category and contract.
Need a Quote for Roof Support?
Send the exact model if known, mine conditions, quantity, destination, preferred trade term, and document requirements. We will reply with the open technical questions and next steps.
