Project Documents on Request

We do not publish generic catalogues, because a generic catalogue is not what gets a building approved. Documents are prepared against your project and issued directly.

Everything listed below is produced for a specific project — your dimensions, your site loads, your jurisdiction. Tell us which document you need and what it is for, and it comes back prepared rather than pulled off a shelf.

Buyer questions

About Project Documents

Do you have a product catalogue PDF?

We do not publish a generic catalogue. Drawings and a spec sheet are prepared for your project and returned with a fixed price, which is more useful than a catalogue in almost every case.

How do I get CAD files?

CAD files are issued on request via WhatsApp, appropriate to your project stage, rather than published for open download.

Are material certificates included?

Yes. Material certificates and load-test reports are supplied per order.

Can I get the engineering before ordering?

You see drawings and a spec sheet with the fixed price, before any deposit. Full stamped calculations are prepared as part of the project engineering.

What do you need to prepare a quote document?

Product type, quantity or dimensions, destination country and port, any code requirements, and a sketch if you have one.
