Projects — built to order

Built for your site.
Not picked from a shelf.

Cold rooms, office and hospitality fit-outs, oxygen and ozone plants. You describe the site and what it has to do; our engineer reviews the drawings; our team quotes the whole job as one written offer — supply, inspection and, where you need it, installation.

  • 22 project lines, 61 reference builds to start from
  • The assistant runs a site-and-capacity interview, not a quantity one
  • One contract, one invoice, pre-shipment inspection on every project

Tell me what you need made or sourced. I search what we already supply, work out the specification a factory will ask for, and draft the inquiry for our team.

How a project runs

Seven steps, one point of contact

The same sequence for a cold room and for a hotel floor. Nothing is manufactured until you have approved drawings and a written quote.

  1. You brief itSite, capacity, drawings or photos — to the assistant or to our team
    Day 0
  2. Engineer reviewWe check the site data and come back with questions, not assumptions
    2–5 days
  3. Design & drawingsLayout, specification and a bill of materials for your sign-off
    With quote
  4. Written quoteSupply, freight, and installation where you want it — one offer
    With quote
  5. ProductionAgainst the approved drawings, with a sample or mock-up where the line allows
    Quoted
  6. Pre-shipment inspectionAgainst the drawings, with photos, before payment is released
    Before release
  7. Delivery & commissioningFreight and customs handled; our installers or your contractor on site
    ✓

Timings are typical, not promises — every project is quoted on its own drawings.

Why it is a project, not an order

A cold room is sized to the product going into it and the heat coming through its walls. A hotel floor is sixty pieces that have to arrive as one matching batch. A treatment plant is engineered to a water analysis. None of that can be picked from a list — so we do not pretend it can.

What you get instead: one engineer who owns the drawings, one contract, one invoice, and an inspection against the drawings before anything ships.
