Refuse Chute Doorset · SS304

Built to
outlast
rust & fire.

We recommend this independently certified, corrosion-resistant SS304 doorset as the replacement standard for the estate's refuse chute doors — ageing doors are prone to rust and can lose fire-safety performance over time.

Refuse Chamber · Block 176 (4/16)
New SS304 stainless steel refuse chute doorset installed at Block 176
TÜV SÜD PSB Certified 132 MIN Integrity
Field Replacement

Same chamber. New standard.

An actual doorset replacement at Block 176 — the rusted mild-steel original swapped for the SS304 doorset, same opening, same signage position.

Before: corroded original refuse chute door with visible rust Before
After: new SS304 stainless steel fire-rated refuse chute door After

Corrosion on the original door's face and hinges is typical after years in a high-moisture chute chamber — and it's the first place fire-integrity performance starts to fail. The SS304 replacement is built specifically to resist that environment.

Tested Performance

Exceeds the 2-hour requirement.

Tested to BS 476: Part 22:1987 by TÜV SÜD PSB Pte Ltd, a SAC-SINGLAS accredited body. The doorset remained intact for the full test — concluded by mutual agreement, not by failure.

132Minutes Fire Integrity — BS 476: Part 22

Against a 120-minute (2-hour) requirement — a 12-minute margin verified under independent test conditions.

Why estates upgrade

Three things that separate a doorset from a door — built for the chamber it lives in, not just the opening it fills.

MATERIAL

SS304 Stainless

Corrosion- and rust-resistant construction, built to outlast the harsh, high-moisture chute chamber environment that breaks down mild steel within a few years.

SAFETY

Independently Fire-Tested

132-minute integrity rating under BS 476: Part 22:1987, verified by TÜV SÜD PSB — exceeding the 2-hour statutory requirement with margin to spare.

HARDWARE

Purpose-Built

Reinforced steel frame, three heavy-duty stainless hinges, mortise lockset and a self-closing door closer — specified for chute doors, not adapted from general doors.
