Roof Box for GMC Sierra: Mining Sites
This roof box is the version most often ordered for mining sites on the GMC Sierra. It is supplied to a written specification covering material, dimensions, finish and packing, and that specification stays on file — so a repeat order is a reorder, not a new negotiation.
What usually goes wrong is ordinary: documentation that arrived after the container shipped, or packing that arrived crushed at the port. Both come from a specification that was never written down.

Fitment notes
Check whether the mounting points on your market version match the catalogue drawing — regional variants are the usual cause of a wrong first order.
Ordering checklist

- State the duty cycle; mining sites is not the same specification as occasional use.
- Approve a sample built from bulk material.
- Fix packing and marking before the first container.
- Inspect before balance payment.

Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

What is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
