About PDE

PDE

Pro Design & Engineering (Pty) Ltd
Established 2020 · Pretoria

We don't replace your engineers. We step in when a job needs specialised input, deliver it properly, and step back out.

No overhead

Engage PDE per project or per drawing. No recruitment, no idle capacity on your payroll.

Signed off correctly

Design and calculations prepared and checked by ECSA-registered engineers.

Workshop-ready output

Drawings your fabricators can cut and weld from, with the documentation your client's QA team will ask for.
