Six workers. Five days. One 1,000 m² insulated building shell.

That's the speed PU sandwich panels make possible — but fast installs only last if they're done right.

In 15 years of exports, we've seen most insulation failures happen at the joints, not in the panels. Follow these rules and your building will perform as designed for 20+ years.

Before you start

Store panels flat and off the ground, protective film on until the last minute
Check the substructure is level — bad framing makes perfect panels fail
During installation

Cut with a carbide-tipped blade at low speed — never an angle grinder, the heat damages the coating
Apply PU sealant foam at every vertical joint before tightening; a hidden gap is a thermal bridge you'll pay for every month
Fix through the metal face into the frame, spacing per the layout plan — typically 300–500 mm
Handle panels by the edges only, and never walk on unprotected roof panels
After the last panel

Peel the film, then seal every fastener head — that's where rust and leaks start
Inspect joints from both sides; re-foam anything you're not sure about
Order panels cut to your exact lengths and you'll skip most of the on-site cutting altogether — less waste, less labor, fewer mistakes.

Not all rock wool panel factories are the same. A cheap panel saves you 5% — a failed insulation test costs you the whole project.

Here's what happens inside our 20,000 m² plant before your panels ever reach a container:

1. RAW MATERIAL CONTROL Rock wool cores are tested on arrival — density and fire resistance checked before a single roll enters production. Substandard batches never make it to the line.

2. PRECISION PRODUCTION Continuous foaming and lamination lines run with computer-controlled thickness tolerance of ±0.5 mm. Uniform core density means consistent insulation — panel after panel.

3. QUALITY AT EVERY STAGE Every batch is sampled and tested: • Fire performance — A2 / B1 / B2 / B3 rated cores for your required standard • Thermal conductivity — down to 0.038 W/m·K • Adhesion and peeling strength, verified before packing

4. PROTECTED SHIPPING Panels are stacked with corner protection, wrapped in PE film, and strapped to the frame. 20+ years of export experience — damage claims are a rarity, not a routine.

THE NUMBERS THAT MATTER:

500,000+ m² annual production capacity
Panels from 50 mm to 200 mm thickness, any length you spec
30–35 days from confirmed order to loading at port
Exported to 40+ countries across Europe, Middle East, Africa, and Southeast Asia
Your project needs insulation you can trust — not a gamble wrapped in metal.

Send "ROCK WOOL" and we'll share our full technical datasheet with fire ratings, thermal values, and factory photos.

Every sandwich panel looks the same in photos. The difference shows up at customs — and at project handover.

Certificates aren't paperwork. They're your passport to projects in Europe, the Middle East, and beyond.

WHAT SHIPS WITH EVERY ORDER:

CE CERTIFIED (EN 14509) The standard EU construction projects require. Fire rating, thermal performance, load-bearing — independently verified to European performance levels.

SGS INSPECTED Third-party lab reports you can hand straight to your client. Real data on fire resistance, insulation value, dimensional tolerance. Not our claims — a lab's findings.

ISO 9001 CONTROLLED Every batch runs through the same audited process — from steel and core material to foaming and packing. Traceable production. Stable quality. Batch after batch.

WHAT THAT MEANS FOR YOUR PROJECT: • Faster approval — no surprise re-testing on site • Smoother customs clearance and tender bidding • A defensible answer when your client asks the hard questions

Trusted by contractors in 40+ countries. Typical lead time: 28 days from order to port.

Want to see the proof? Message "CERT" — we'll send our CE certificate, a sample SGS report, and the full spec sheet.

Two cold rooms. Same size. One electric bill 30% lower.

The difference? The panel in the wall.

Most operators buy insulation on price alone — then watch energy bills climb for years. That's why our polyurethane sandwich panels are built for buyers who do the math.

What changes when you use shandongshanghe PU panels:

Cooling costs drop — 0.022 W/m·K thermal conductivity locks cold air in. Many clients report up to 30% lower cooling energy year-round.
Made on a controlled line — high-pressure continuous foaming, uniform 40 kg/m³ core density edge to edge. No voids, no weak spots, no cold bridges.
Protected in transit — sealed bundles and edge guards on every load, checked piece by piece before shipping. Panels arrive flat, dry, ready to install.
Tested before it leaves — every batch passes density, flatness, and adhesion checks. Quality reports available on request.
Standard range:

Thickness: 50–200 mm
Width: up to 1150 mm
Length: customized
Fire rating: B1 / B2 available
Cold rooms, freezer warehouses, cleanrooms, or prefab buildings — we size, quote, and deliver on your schedule.

Get your free project plan + quotation within 24 hours. Send your dimensions and site requirements — we'll reply with panel specs, quantities, pricing, and client references from past projects. No obligation.

Two warehouses caught fire the same night. One burned to the ground. The other reopened in 3 weeks.

The difference wasn't luck. It was rock wool.

Rock wool sandwich panels are why modern industrial buildings survive what used to destroy them:

Fire doesn't spread through them

A1-class non-combustible core (EU standard)
Melting point above 1000°C — protects the steel frame underneath
Slows fire spread, buys evacuation time, lowers insurance premiums
They cut energy costs every month

Thermal conductivity as low as 0.038 W/m·K
Cold storage holds temperature with up to 30% less energy
Keeps heat in during winter, out during summer — year-round savings
They build quieter, cleaner workplaces

Sound insulation for noisy production lines
Smooth, hygienic surfaces for food & pharmaceutical plants
No dust, no exposed fibers after installation
How we make sure quality isn't a gamble:

Continuous production line: steel coil → profiling → rock wool core → auto lamination
Every batch tested: fire rating, bond strength, peel test
Panel widths 950/1150mm, length fully customizable
Export packing: edge protection + shrink wrap — panels arrive flat and scratch-free
One material. Fire safety, energy savings, and sound insulation in a single panel.

Wasting 30% of your cooling energy through the walls?

That's what unprotected steel buildings lose every month. Our PU sandwich panel stops it at the panel.

How it's made:

• 0.5mm galvanized steel on both sides, produced on a continuous line • 45 kg/m³ closed-cell PU core — injected, not glued, zero hollow spots • CNC precision cutting: length tolerance ±1mm, sealed edges against moisture

What it does for your project:

• U-value as low as 0.22 W/m²·K — a 100mm PU panel insulates like a 1.2m concrete wall • Fire-rated options up to Class B (rock wool core available up to Class A) • 30%+ lower cooling costs for cold storage, year after year

Why you can trust every shipment:

• Every batch density-tested and pressure-checked before packing • 3-layer export wrapping — panels arrive dent-free after 6,000 km ocean freight • 40,000+ m² shipped to 30+ countries last year alone

Client story:

"Our freezer room used to run 22 hours a day. With Shanghe panels, it runs 14. Energy bill down 36% in the first quarter." — Cold chain operator, Middle East

Why do so many building owners still repaint their facades every 3 years?

Salt spray. UV fading. Cracks that let water in. The paint peels, the concrete stains, and the cycle starts again.

That's why coastal hotels and resort villas are switching to our metal siding panels — and never repainting again.

What they get instead:

20+ years of weather resistance, zero repainting or resealing
Carved 3D textures that mimic wood grain and stone — without rotting or cracking
Pre-painted PVDF coating that survives salt air and intense sun
Lightweight panels (4–6 kg/m²) that install directly onto existing walls
No demolition needed — old facades are covered, not torn down
Real numbers from a resort project in 2025:

3,000 m² of facade renewed in 18 working days
Labor cost cut by 60% vs. stone cladding
First inspection after 12 months: zero visible wear
Owners stopped budgeting for repainting. They budgeted once — and moved on.

"Three seasons on the coast and the panels still look brand new." — Resort owner, Philippines

What if your building could look hand-carved — installed in just 2 days?

That's exactly what happened on a 1,200 m² commercial project last month. No scaffolding towers. No welding crew. No 3-month construction schedule.

Here's how our metal carved panels changed the game:

Panel size: 1220×2440 mm, custom lengths available
Weight: as light as 4–6 kg/m² — one worker handles a panel easily
Fixing: screw-fixed or hook-and-slot on a simple steel frame, no welding
Speed: a 4-person crew covered 300 m² per day on site
Finish: pre-painted PVDF/polyester coating — zero on-site painting
Why owners choose them:

Instantly upgrades hotels, villas, retail facades, gas stations
Weatherproof for 20+ years with zero maintenance
Fire-retardant core options for stricter building codes
Replaces heavy stone at a fraction of the cost
The result? A facade that looks like months of craftsmanship — delivered in days.

"Installation was the easiest part. Our crew finished 3 days ahead of schedule." — Project manager, Kenya
