Steel–aluminium armored entrances: structure, security and finish
Why a steel structural base and aluminium-facing strategy can balance rigidity, surface durability and architectural expression.

A hybrid material strategy
Steel–aluminium armored entrance doors combine a steel structural base with aluminium-facing or decorative elements. The steel frame and reinforcement provide rigidity, while the aluminium surface broadens the available textures, colours and sculpted details.
What to review with the supplier
- Door-leaf and frame construction, including material thicknesses and reinforcement.
- Lock, locking points, hinges and anti-pry details for the final leaf size and weight.
- Seal layout, core material and threshold treatment where acoustic or thermal performance matters.
- Finish sample, exposure class and maintenance guidance for the destination climate.
- Installation interface, anchorage and tolerances shown on approved shop drawings.
Avoid generic performance assumptions
Security, acoustic and thermal values vary with size, hardware, glazing and test specimen. A useful quotation therefore links the proposed configuration to controlled drawings and the evidence available for that configuration instead of relying on a category name alone.
