Choosing Depth by Span and Wind Zone

Work from the girt spacing and the design wind pressure, then check the thermal target:

Elevation duty	Depth to specify	Why that depth
Sheltered sites, girts at 3 m or less	50 mm	Lightest to handle; the ribs carry the span without help
Factory elevations, girts at 4-5 m	75-100 mm	Deeper section resists oil-canning when the sun is on it
Sheds with girts at 6 m and beyond	100-150 mm	Stiff enough to cross wide bays with no intermediate rail
Exposed coastal or hilltop positions	150-200 mm	Holds 1,200 Pa and more; deepest section against uplift
Cyclone and typhoon wind regions	100 mm minimum	Tested at 1,200 Pa and above, with fixings sized to the zone

Depth and Rib Combination

Rib height is fixed by the profile, depth by the duty. Shallow 50 mm boards line internal partitions and sheltered elevations; 75-100 mm is the normal call for factory walls on girts at 4-5 m; 150-200 mm is used where the board spans 6 m or where the site sits in a high wind region. The core is rigid polyurethane throughout - EPS is not offered in this profile.

Declared lambda	0.022-0.024 W/(m.K)
Core density	38-43 kg per cubic metre
Absorption	1.5% maximum
Compressive strength	150 kPa or better, confirmed against the batch test report
Service life	15 to 25 years in ordinary outdoor exposure
Joint	Tongue and groove with a sealed overlap at the rib ends

Surface Material & Coating Options

Colour and Finish

Four tones are held in stock - white, light grey, sky blue and terracotta - and white is the one that ships most often. Any RAL reference can be matched, and the corrugated profile comes in several rib pitches so the shadow line across the elevation can be set deliberately.

Application

Built for steel-framed factories and wide-span warehouses where the enclosure has to go up fast and then stay flat. The ribs read as a deliberate rhythm along a long elevation, and the board works equally well on modular workshops and agricultural sheds, where saving steel in the frame matters more than anything else.

Project

A grain handling and storage terminal at Kandla, India, was clad in 2020 with close to 9,000 m2 of 100 mm corrugated board fixed to girts at 5 m centres. Monsoon rain and a salt-laden coastal atmosphere drove the specification, so clearance of water off the rib face and coating durability were examined first. The ribs let the board span the wider girt centres without intermediate rails, which cut steel tonnage, and the enclosure was closed three weeks ahead of the programme.

Customization & OEM Service

Rib pitch, depth, cut length, facing gauge, coating weight and colour are all set per order, and we produce under your own brand with your labelling and paperwork. Coating systems are chosen against UV load and atmospheric category, and sample lengths in the specified profile are sent for approval before the order is released.

Certifications & Compliance

The works holds ISO 9001, 14001, 45001 and 50001 certification, and coated coil is bought to EN specifications with mill certificates kept per batch. Fire classification is backed by reports to EN 13501-1 and GB 8624, and we supply the document pack that tender submissions usually ask for.

Manufacturing Strength & Quality Control

Track record: sixteen years spent making sandwich panels specifically for export, into more than thirty countries.
The line: coil is levelled and roll-formed to the chosen rib profile, foam is injected and bonded under pressure, then the board is cured, cut to length, edge-trimmed, slotted, filmed, inspected and packed without leaving the conveyor.
Incoming checks: every coil and every drum of chemicals is inspected and released before it reaches the line.
During the run: rib height, cover width, bond strength and core continuity are sampled batch by batch.
Beyond the line: drawings, export quotations, certification packs and shipping documents are handled by one team.

Lead Time, MOQ & Delivery terms

Item	Detail
Lead Time	Stocked profiles leave the works 7-10 working days after deposit. Made-to-order depths take 12-18 working days; sample lengths are expedited in 3-5 working days.
Order size	Trial quantities welcome - a single pallet is enough to start.
Delivery terms	FOB, CIF or DDP, quoted against the port you nominate.
Payment	Telegraphic transfer or letter of credit; terms fixed per order.
Packing	Face filmed, corners guarded, palletised and stretch-wrapped for the sea leg.

Service and Support

Help is available online and over video for fixing sequence and detailing. Where a defect is ours, boards are replaced and the remedy is put in writing rather than argued. Through the order you get selection advice before it, progress photographs and packing images during it, and troubleshooting after it.
