Six steel routes explained
Crittall-style describes a look — the specification must still name the actual system and thermal route.

Steel pricing follows the system and use
No single per-square-metre headline covers welded steel, look-alike aluminium and heritage-bar uPVC.
External thermally broken steel, internal cold steel and steel-look aluminium are quoted on drawings, sizes and finish — not from a generic online calculator.
See the steel price hub for guide bands once your route is shortlisted, then request an itemised written quote.

Which steel for which opening?
Match the product to the heated or internal use
Survey confirms structure, thermal break requirement and compliant specification.
| Route | Often suits | Check first |
|---|---|---|
| Thermally broken external steel | Heated external windows and doors | U-value route, glazing and sightline target |
| Cold / interior steel | Room dividers and unheated spaces | Condensation risk if used on heated elevations |
| Steel-look aluminium | Slim grids with lower maintenance | Joint detail vs genuine welded steel |
| Heritage-bar uPVC | Traditional appearance on a uPVC budget | Grid width and joint authenticity |
Steel questions
Before you specify steel
Common steel and Crittall-style questions.
01Do you supply Crittall?
We supply independent steel and alternative systems. We do not claim affiliation with Crittall Windows Ltd — the quote names the actual manufacturer and system.
02Can cold steel go on an external wall?
Only where the use and building physics allow. Heated external openings normally need a thermally broken route — survey and specification confirm.
03When is steel-look aluminium enough?
When maintenance, budget and sightline targets suit aluminium profiles. Compare joints and grid proportions on the written quote, not from marketing images alone.
