Materials

Four materials,
all UK-sourced.

We hold raw stock in all four materials at the Kent factory. No waiting on a steel mill — that's the reason our lead times don't slip.

Mild Steel
Gauge1.5 – 3 mm
FinishPowder coat RAL 7035 std
IPIP65 · IP66

Cost-effective for protected environments. Powder-coated to RAL colour of choice. Best suited for indoor or sheltered installations where stainless or GRP isn't required.

304 Stainless
Gauge1.5 – 2 mm
FinishBrushed or bead-blasted
IPIP66

General-purpose austenitic grade. Good corrosion resistance in most environments. Standard for food, beverage and pharmaceutical where chloride exposure is limited.

316 / 316L Stainless
Gauge1.5 – 2 mm
FinishBrushed or electropolished
IPIP66

Molybdenum-enhanced grade with superior chloride resistance. The marine and offshore standard. Specified for coastal, chemical and any environment with salt-spray exposure.

GRP / Polyester
GaugeP5 / SMC moulded
FinishMoulded, RAL 7035 std
IPIP66

Glass-reinforced polyester. Corrosion-proof, lightweight, non-conductive, non-magnetic. Specified where metallic enclosures are unsuitable — chemical, coastal, GRP-mandated specs.

IP ratings

Plain-English
ingress protection.

IP65 and IP66 are the two ratings relevant to most industrial enclosures. The numbers determine whether your enclosure survives a jet wash or a pressure wash. For the full classification methodology, see IEC 60529.

IP65
Dust-tight. Low-pressure water jets from any direction. Outdoor standard minimum.
IP66
Dust-tight. Powerful water jets. Pressure washing, heavy rain. Recommended for outdoor industrial.
Good to know

IP65 and IP66 are not interchangeable. IP65 protects against low-pressure jets from any direction; IP66 withstands powerful jets and pressure washing. For most UK outdoor industrial installations, IP66 is the practical standard.

Common questions

Industrial enclosures, answered.

If your question isn't here, our engineering desk answers the same working day.

What is the difference between 304 and 316 stainless steel enclosures?
304 stainless steel is a general-purpose austenitic grade with good corrosion resistance in most environments. 316 (and 316L) adds molybdenum, which significantly improves resistance to chlorides, salt spray, seawater, and chloride-containing cleaning agents. For marine, offshore, coastal and pharmaceutical applications, 316L is the standard choice. For indoor food and beverage or general industrial environments where chloride exposure is limited, 304 is typically sufficient and lower cost.
What is a GRP enclosure?
A GRP (glass-reinforced polyester) enclosure is a non-metallic electrical enclosure moulded from fibreglass-reinforced polyester resin. GRP enclosures are corrosion-resistant, lightweight, non-magnetic and non-conductive, making them suitable for aggressive chemical environments, coastal installations and applications where metallic enclosures are not appropriate. They are commonly specified for water treatment, chemical processing and coastal utility installations.
What IP rating do I need for outdoor use?
For general outdoor use, IP65 is the minimum — dust-tight and protected against low-pressure water jets from any direction. IP66 is recommended where the enclosure may be subject to powerful water jets, pressure washing or heavy rain, and is the practical standard for most UK outdoor industrial installations. IP67 is required where temporary submersion (up to 1 metre for 30 minutes) is possible. Note that IP67 does not imply IP66 — if you need both, specify both.
What is the difference between a junction box and a terminal box?
A terminal box contains terminal blocks — it is used to connect, distribute or terminate cables in a fixed installation. A junction box is a broader term for an enclosure used to connect cables, which may or may not contain terminal blocks. In practice, our iTB range is supplied with or without terminals to customer specification, and the terms are often used interchangeably in the UK industrial market.
Can you supply custom-sized enclosures with a short lead time?
Yes — custom sizing is standard for us, not a special order. We manufacture enclosures to your exact dimensions from 80×80 mm to 600×600 mm (terminal boxes) and up to 2 metres for floor-standing cabinets. We hold raw stock in all four materials, quote the same working day, and deliver the majority of orders in 3–4 weeks.
