Non-Fire Rated Riser Doors

Standard Service Access.
Without the Fire Penalty.

Not every service shaft penetrates a compartment line. Where a fire rating isn't required, our non-fire rated R57 and R53 riser doors deliver the same UK-manufactured build quality at a more competitive price point — 3-5 day lead times, made to measure up to 2400×1000mm.

Riser doors provide service access to vertical mechanical, electrical and plumbing shafts. Where the shaft does not form part of a fire compartment line, a non-fire rated door is the appropriate specification — saving cost while still delivering the same robust steel construction, three-point locking and finish options as our fire-rated R51 range. Manufactured in the UK with 3-5 day lead times.

When non-fire rated is the right call

Same build, no fire penalty

FAQ

Common questions

How do I know if I need a fire rating or not?

The fire strategy for the building tells you. Service shafts that pass through compartment walls or floors must have fire-rated access. Shafts wholly within a single compartment — typically plant rooms, secondary risers in single-tenancy spaces — usually do not. Your fire engineer or Building Control will confirm.

How much cheaper is non-fire rated vs R51?

Typically 20-30% lower on the door alone, depending on size and configuration. The bigger saving comes from no intumescent-seal install, no fire test certificate paperwork, and no compartmentation sign-off requirement. Ask for a quote with both options if you're unsure.

Is the steel grade the same?

Yes. Our non-fire rated R57 and R53 doors use the same Zintec steel and 1.2mm/1.5mm thickness as the fire-rated R51 range. The only differences are the omission of intumescent seals and the absence of fire-test certification.

Can I get the same locks and finishes?

Yes. 3-point locking, polyester powder coat in any RAL colour, single or double doors — the full spec menu is available on non-fire rated as on fire rated.
