Armour plate protection classes: reading the specification properly
How ballistic protection levels are defined, why plate hardness alone tells you nothing, and what fabrication rules keep the protection intact.
Mill lead time versus stock: what the wait really costs you
A rolling programme can be months away. How to decide what to buy from stock, what to order against a schedule, and what to hold yourself.

UHMW-PE or steel liners: stopping material sticking instead of just resisting wear
When the real problem is build-up, carryback and noise rather than abrasion, a polymer liner outperforms hardened plate.

Schedule, NPS and wall thickness: ordering pipe without ambiguity
Why the same schedule means different walls at different diameters, and what to state so the pipe you receive is the pipe you planned.

Pickling and passivation: the step that decides whether stainless stays stainless
Welding, grinding and even handling leave stainless less corrosion resistant than it arrived. How to restore the passive layer properly.

Cutting tolerances: what to specify so the parts actually fit
Laser, plasma and waterjet each leave a different edge. Specify the process and the tolerance class, not just the profile.

What an EN 10204 3.1 certificate actually proves — and what it does not
The difference between 2.1, 2.2, 3.1 and 3.2 documents, and why traceability to a heat number is the part that protects you.
