Good steel shouldn’t
be a luxury.

Good steel shouldn’t be a luxury reserved for the most generous budgets. TB Pro was developed because a thermally broken steel door reliable, well-made, properly insulated should be achievable across a wider range of projects without stepping down to inferior materials.

Suitable for both internal and external applications, it combines drop-down seals, soft-closing hardware compatibility and double glazing units up to 32mm with the clean architectural lines that steel consistently delivers. It’s a practical system, honestly specified and because every door is made to order, it remains fully adaptable to the dimensions, glazing and hardware requirements of your project.

Standard in RAL 9005 with custom options available.
