Wire and tube

• Carbon steel wire — the default for retail kitchen and home organization products
• Stainless steel wire and flat rail — for corrosion resistance without a coating

Sheet metal

• Stainless steel stampings — drain boards, rails, brackets

Plastic parts

• PP trays, castors and inserts (sourced to your specification)

Finishes

Finish	Typical use	Constraint
Powder coated	Any RAL tone, matte or gloss	Must pass the food-contact route of the destination market
Chrome plated	Premium retail appearance	Scratches expose the substrate
Electropolished	Stainless parts needing corrosion resistance without coating	Stainless substrates only

The finish is a compliance decision before it is a cosmetic one — see Which certifications can you provide for our market?

Wire diameter is derived, not chosen. It follows from the load case:

Expected load per tier
  → span between supports
  → number and spacing of cross wires
  → required wire diameter
  → weld pattern

Two racks with identical outer dimensions can use different wire gauges and behave completely differently under a full dishwasher load or after a year of use.

So the useful input from you is the load case (what sits on it, how much, and whether it goes in a dishwasher), not a target diameter. We will come back with the gauge and the weld pattern that satisfy it.

MOQ is not a fixed number — it is a consequence of three things:

1. Tooling — a new wire-forming jig only pays for itself above a certain volume
2. Finishing batch — powder coating and plating run in batches, so very small orders get expensive per unit
3. Material order — wire is bought by the tonne, and a small order may leave unusable offcuts

Because of that, we quote MOQ together with tooling cost and unit price, so you can see the trade-off instead of receiving a single arbitrary number.

Certification is market-specific, so the answer depends on where you are selling:

Market	Food-contact route	Also typically requested
North America	FDA 21 CFR	California Proposition 65, NSF
European Union	EU 1935/2004	REACH, RoHS
Germany	EU 1935/2004 plus LFGB	REACH, RoHS

On top of the market-specific items we hold ISO 9001 and can arrange BSCI / amfori social compliance audits and SGS material test reports.

Two practical points worth flagging:

1. Test reports are issued against a specific material and finish. Change the coating supplier and the report may no longer apply.
2. Reports are per order, not off the shelf. Documents that are public are listed on the certifications page; others we issue on request with the quotation.

Yes, and on bulky wire products it is usually the largest controllable cost in the whole programme.

A welded wire frame is mostly air. Shipping that air across an ocean is pure waste. A KD (knock-down) structure ships flat, which cuts container volume substantially — so when you compare suppliers, compare cubic metres per unit, not just unit price.

Two things to weigh before choosing KD:

• Assembly effort moves to your customer. For retail this has to be either tool-free and obvious, or a stated feature (“assembles in under a minute”).
• Rigidity perception. A KD frame must still feel solid once assembled. That is a joint and locking-tab design problem, and it is where the engineering effort goes.
