Compare warranties and coatings to pick the best metal siding for your project. This helps it last a long time and keep its color.
When you put metal cladding outdoors, three problems can happen. UV rays slowly break down the surface coating. Moisture starts chemical reactions along the panel edges. Temperature changes make the metal expand and shrink many times.
When you put metal cladding outdoors, three problems can happen. UV rays slowly break down the surface coating. Moisture starts chemical reactions along the panel edges. Temperature changes make the metal expand and shrink many times. Each time, it stresses the link between the metal and its protective layers. You need products that are built to fight these forces.
WILLSTRONG makes different panels to handle each outdoor problem. Aluminum composite panels have a PVDF coating. This coating blocks UV light well and keeps the color stable in direct sun. Fire-resistant panels use a mineral-filled core that stays steady during temperature changes.
Honeycomb panels have an aluminum core glued between two thin metal skins. This design spreads thermal stress evenly over the whole surface.
The PVDF coating on these siding panels stops moisture damage by creating a waterproof barrier. In standard salt-spray tests, these panels show very little edge wear after long exposure. The aluminum honeycomb design keeps water from gathering inside the structure. You get a panel system built for tough outdoor conditions. Hidden fixing systems remove exposed screw heads. That takes away spots where water can get in. Each wall panel stays sealed against rain and condensation.
WILLSTRONG has given metal cladding systems to clients in many climate zones since 1995. The company holds over 40 certifications for fire resistance, weather tightness, and material makeup. Each certification needs independent lab tests. This gives you confirmed performance data for your project specs.
One well-known project uses WILLSTRONG metal cladding at Charles de Gaulle Airport in Paris. The panels stand up to jet exhaust, chemical cleaners, and constant temperature changes. This job needs strict fire safety rules and long-lasting durability.
For your project, you get corrosion-resistant materials built on years of engineering improvement. You can pick corrugated metal siding or flat panel systems that have proven field performance. These systems lower maintenance costs over their lifetime.
Zinc metal siding is not like painted metal cladding. Instead of using a coating from the factory, zinc protects itself through a naturally developing patina layer.
Zinc metal siding is not like painted metal cladding. Instead of using a coating from the factory, zinc protects itself. RHEINZINK makes its zinc from titanium zinc that is 99.995% pure. This high purity gives the metal self-healing properties.
ZNBase Zinc, 99.995% Purity ... gives it corrosion resistance and a self-healing patina layer.
When you put this siding outside, the surface reacts with air and water. That reaction creates a patina layer. The patina works like a natural shield against rust. If the surface gets scratched, the patina grows back over the scratched spot. This material fixes its own protective layer.
How fast the patina forms depends on your local weather. Experts say it can take from six months to five years or more to form. Wetting and drying cycles make it go faster. Patina forms slower on walls than on slightly slanted roofs. You can expect faster patina growth near the coast where it rains often.
A big plus of zinc cladding is that it lasts a long time. The patina layer works for many years without needing new paint or coating. You take care of it less than painted metal panels. This makes zinc siding a good choice for buildings that are hard to reach.
Warranties for titanium zinc products often last much longer than for painted ones. Companies back these products for decades because the patina doesn't wear out like a coating does. Feedback from old installations backs this up. Building owners say zinc surfaces still protect well after many years outside.
The material also deals well with temperature changes. Zinc grows and shrinks as temperature changes. The patina layer moves with the metal instead of cracking. This bendiness stops edge problems you might get with hard coatings. For your project, zinc cladding offers a strong solution that works with nature instead of against it.
PAC-CLAD makes metal siding panels using a simple engineering plan. The finish shields the steel or aluminum base from weather and helps protect long-term appearance.
PAC-CLAD makes metal siding panels using a simple engineering plan. The finish shields the steel or aluminum base from weather. A weak finish breaks down first. Then moisture gets to the metal. Then rust begins. PAC-CLAD fixes this with a 70% PVDF coating system. This coating uses Kynar 500 or Hylar 5000 resin. The high resin content forms a thick shield against UV rays. Sunlight breaks down weaker paints through a process called chalking. The 70% PVDF finish fights off this breakdown. Color stays steady under strong sunlight. The coating also stops moisture from reaching the metal below.
Coating System | Composition | Purpose |
|---|---|---|
PAC-CLAD finish | 70% Kynar 500 / Hylar 5000 PVDF | Resists fading, chalking, and color change under sunlight |
Finish warranty | Up to 40-year finish warranty | Supports long-term color and finish performance |
You can pick hidden fastener siding panels for a clean look. These metal wall panels hide the screws behind the panel edge. Water cannot pool around open fasteners. This design choice makes your cladding system last longer.
PAC-CLAD supports its metal siding with a 35-year finish warranty. This warranty covers cracking, peeling, and color fade. The company calls it a non-prorated finish warranty. That means the coverage does not shrink over time. You get full protection for the whole warranty period. Some colors and metallic finishes may have different terms. You should check the exact terms for your chosen color.
Contractors share good results with these metal panel systems. They note easy installation and steady quality across orders. The warranty gives building owners peace of mind. You know the finish will last for decades. This matters for metal cladding on tall buildings. Replacing failed panels costs much more than the first material.
For your project, compare the warranty length with other metal siding choices. A 35-year finish warranty shows the maker trusts its coating technology. You can also ask for test data on salt-spray resistance. This data shows how the finish holds up near the coast. Pair a strong finish with proper installation. Then your metal siding panels will give long-term performance.
EDCO builds its metal siding around a steel substrate. The RealGrain™ finish adds a textured surface designed to work with the steel core as one system.
EDCO builds its metal siding around a steel substrate. The RealGrain™ finish adds a textured surface that resists cracking, chipping, peeling, and splitting. You get a strong and durable panel when the steel core and the finish work as one system. Rust perforation is the main failure mode for steel cladding. EDCO addresses this directly by covering substrate deterioration in writing.
The warranty structure tells you how the company views long-term risk. You must register within 60 days of installation and provide proof of purchase. The table below shows the core terms.
Category | Terms |
|---|---|
Coverage period | First 20 years: full material and installation labor cost. Beyond 20 years: up to 10% of original material cost |
Processing fee | $100.00 per claim, waived if installed less than 3 years before the claim |
Transferability | First transferee only, within 20 years of installation |
Exclusions | Saltwater within 1 mile, natural disasters, improper installation, normal wear |
Coastal sites test any metal cladding system hard. Salt accelerates corrosion on cut edges and fasteners. EDCO excludes saltwater within 1 mile from coverage, so you should confirm your site distance before you specify these metal wall panels. Inland industrial zones bring a different stress: chemical pollution and acid rain. The warranty also excludes chemical damage, which means the finish must handle those loads on its own.
For commercial properties and HOAs, coverage runs 20 years on material and labor. That period matches the typical repaint or recoat cycle for painted metal panels. You avoid mid-cycle replacement costs during the covered window. Pair this cladding with proper flashing and drainage details. Water that drains away from panel edges cannot sit and attack the steel. These metal cladding systems reward careful detailing with a long service life.
Comparing coating systems, substrates, industry standards, panel construction, warranties, and installation helps define the requirements for a long-term cladding system.
Start by comparing coating systems. PVDF coatings use 70% Kynar 500 resin and resist fading well. SMP coatings offer a 20 to 30 year warranty. PVDF gives a 40 year film integrity warranty. Check which coating each supplier uses. This is a big difference among metal cladding companies.
Next, look at the metal under the coating. Steel with an aluminum-zinc coating has two layers of protection. Aluminum stops moisture. Zinc gives itself up to protect the steel. ASTM A792 sets the galvalume standard. This resists corrosion well. Aluminum substrates weigh 2.7 g/cm³. They work well in coastal areas with the right treatment.
Third, check industry standards for metal cladding. ASTM B117 tests how well metal resists salt spray. ASTM E1592 tests how much wind pressure the panels can handle. UL 2218 tests impact resistance. These standards help you choose the right metal cladding for your site. A good metal siding panel passes all three tests.
Panel construction also matters. A metal panel rainscreen system lets air flow behind the panels. This helps dry trapped moisture. Concealed fastener siding keeps screws away from water. Corrugated metal siding uses a simple shape that resists warping. Durable metal cladding starts with good panel design. Proper installation keeps problems away later.
First, ask about salt-spray resistance. Does the product meet ASTM B117? These certifications prove metal panel systems can handle salt. This metal siding resists salt damage well.
Ask about the finish warranty. Is it non-prorated? PVDF from metal makers and contractors often has a 40 year warranty. Ask product suppliers about their coating terms. This protects your metal siding investment over time.
Ask about the installer’s experience. A professional installer sets the right joint spacing for temperature changes. They handle transitions at windows and doors. They keep drainage paths clear. The quality of installation decides if your cladding works as it should. Water problems often come from poor installation, not bad materials. This applies to metal siding for houses and commercial buildings. Choose rainscreen cladding for wet climates.
Take time to compare these factors. The best metal siding matches coating, metal, and installation to your site. Look for metal siding that fits your budget and location. Panels from proven companies last longer. Verify each factor. Do not skip the research phase.
You now have four trusted metal cladding companies to think about. WILLSTRONG offers panels that fight corrosion with PVDF coatings and over 40 certifications.
RHEINZINK uses 99.995% pure titanium zinc that forms a self-healing patina. PAC-CLAD applies a 70% PVDF finish with a 35-year warranty. EDCO provides heavy-duty steel cladding with a lifetime warranty. Ask each supplier for samples. Compare their warranties side by side. This metal cladding approach helps you choose wisely. Durable metal siding comes from material science and system design. Any of these cladding options will give you less maintenance over time. Good engineering is often invisible.
Common questions about warranties, coastal applications, coatings, installation, and residential use.
Check three things: how long it lasts, if it shrinks over time, and what it covers. PAC-CLAD gives a 35-year non-prorated finish warranty. EDCO covers material and labor for 20 years. RHEINZINK backs its zinc for many years because the patina does not wear out. Read the exclusions closely before you buy.
Coastal sites need strong salt-spray resistance. Look for metal panels that pass ASTM B117 testing. WILLSTRONG uses PVDF coatings that block moisture at panel edges. RHEINZINK zinc forms a self-healing patina that resists salt. EDCO excludes saltwater within 1 mile, so check your distance first.
Pick a 70% PVDF coating with Kynar 500 or Hylar 5000 resin. This coating fights chalking and fading under UV light. PAC-CLAD uses this system and backs it with a long finish warranty. SMP coatings cost less but give shorter protection. Your metal siding color stays steady with PVDF.
Yes. Bad installation causes most water problems, not bad materials. A professional installer sets correct joint spacing for temperature changes. They keep drainage paths clear at windows and doors. They use hidden fasteners to remove spots where water can pool. Good detailing makes service life longer.
Yes. WILLSTRONG makes panels for both residential and commercial uses. RHEINZINK zinc works on homes in wet climates. PAC-CLAD and EDCO serve commercial properties and HOAs. Match the panel type to your local weather and building height. Ask each supplier for samples before you decide.
