Swinging Cold Storage Door | FRP

Designed For Coolers and Freezers

Built for cleanliness. Engineered for efficiency.

Our fiberglass cold storage doors are built for a higher standard of durability, hygiene, and corrosion resistance for cooler and freezer applications.

This FRP door was designed to work where commoditized, painted galvanized, walk-in style cooler doors do not. With a void-free foam core and welded frame, these doors eliminate potential harborage and keep your consumers safe.

Cold Storage FRP Door Highlights


Void-Free Construction

CleanCor™technology eliminates voids, preventing moisture buildup and bacteria growth — even in washdown environments.

Easy To Clean & Corrosion-Proof

A molded gel coat exterior stands up to all types of chemicals and corrosion. Plus, it’s easy to clean. Even graffiti wipes off!

Exceeding Industry Standards

Our FRP doors exceed current USDA and FDA cGMP standards, so they’ll stay compliant even when the bar is raised.

Maximized Energy Efficiency

Our cold storage doors are designed with advanced insulation technology to minimize heat transfer and save on energy costs.

Featured Technology:



Nowhere for bacteria to hide

We understand the importance of hygiene in your industry. That is why we developed CleanCor™, a void-free foam core at the center of all our doors.

Without a void-free construction and quality hardware, moisture can collect at hardware penetrations, creating an environment for bacteria to grow.

We have designed a closed-cell core that is inorganic, insulating, and completely void-free from the core to the hardware backing. The resin injection process fills any void in the mold, making our panel the most hygienic in the industry.


Built to last with seamless fiberglass

Our FiberShell™technology creates a truly seamless exterior on all six sides, protecting against bacteria growth and preventing wear and tear.

Our doors are molded — not laminated. While conventional methods press laminate FRP sheets to a core with bonding agents, our fiberglass seamlessly wraps the door panel core material. This approach ensures a longer-lasting product and eliminates harborage areas along the edge of the door.

As a bonus, our FiberShell™exterior is 50% thicker than traditional doors, making it the toughest option available.


The Ultimate Design for Energy Efficiency

Seals that Actually Seal

Our cold storage FRP doors feature milter and splice-free EPDM gaskets. The gaskets securely wrap around the entire perimeter without any joints or gaps, ensuring a tight and effective seal that keeps the cold air inside (and the external elements out).

Premium Foam Insulation

We inject a closed-cell polyurethane core for maximum R-value. The door’s core resists heat flow to maintain the desired temperature in your cold storage facility.

FRP Door Vision Panels


Completely Hygienic Construction

The single flush window is seamlessly integrated into the door with a sloped, void-free retainer.


Highly-Durable Polycarbonate

The FRP vision panel is made with abrasion and chemical-resistant polycarbonate.


Options for Every Environment

We also offer insulated, tempered, fire-rated, heated, and safety-coated glass. Plus, we can provide blast-resistant safety film for USDA and FDA compliance.

Cold Storage Stainless Steel Frame


Durable and corrosion resistant

Made of 16 ga. stainless steel casing style

Excellent thermal performance

5 lb. p.c.f. insulating structural foam injected into face casings and back-trim

Hygienic and easy to clean

Fully-welded vertical and horizontal sections of the frame eliminate seams and harborage areas.

Refrigeration Hardware That Lasts

We curate high-quality, stainless steel hardware to stand the test of time — even in harsh environments. Each cold storage FRP door is made with high-screw retention composites for hardware reinforcement.

With industrial hardware stocked in our warehouses, it’s easy to make last-minute changes in plans — without waiting months to get what you need.

Architectural Details


4″ thick doors are readily available in standard 3×7′ nominal sizes. Custom sizes are available for double doors and 3′ wide openings taller than 7′.


Premium 25-mil gel coat is molded into our fiberglass doors, chemically bonding with the underlying fiberglass resins. This exterior protects against corrosion and deterioration and provides a hygienic surface. Most customers opt for UV-resistant white doors, although other custom gel-coat colors are available.

FiberShell™ Technology

We offer the only fiberglass cooler door on the market — and the only cooler door to be molded all at once with FiberShell™ technology. The front, back, and sides are formed at once through an advanced close-molded process yielding a solid, continuous, and seamless structure of fiberglass. Measuring more than 1/8” inch thick on the face and nearly .375″ thick on the edges, our fiberglass exterior is the thickest of any swinging cold storage door in the industry.

Stainless Steel Casings with WeldWrap™ Technology
  • Industry-leading 16 gauge stainless steel face casings with WeldWrap™ technology come standard with injected 5 lb. per cubic foot polyurethane cores.
  • The vertical and horizontal sections of casing are fully welded together for a seamless, maintenance-free application.
  • The core of the jamb is fabricated from HDPE plastic lumber. Jamb depths are built to virtually any size, accommodating any wall type or depth.
  • This swinging cold storage FRP door panel can also be paired with a conventional white metal casing as well upon request.
Void-free CleanCor™ Technology

The core of our swinging cold storage FRP door was engineered using a combination of advanced polymers for maximum screw retention and premium polyurethane foam for maximum R-value. There are no voids anywhere in the door panel and no harborage areas.

Stainless Steel Vision Panels
  • Standard sizes available: 10×10″
  • Custom size options for frames available upon request
  • Margard-treated polycarbonate glazing for enhanced durability (chemical and abrasion resistant)
  • Additional glazing options: insulated, tempered, fire-rated, heated, and safety-coated glass
  • Blast-resistant safety film option for USDA and FDA compliance
Pre-Mounted Hardware

We utilize the highest quality stainless steel hinges, latches, and hardware from a variety of the best manufacturers in the USA. Chrome plate hardware is available upon request.

What Clients Say

“In Weiland, I was pleasantly surprised to find a door manufacturer that understands what makes a door hygienic for my customers. Most door people have no clue.”
