Commercial Steel Doors

ELT's insulated steel cooler and freezer doors feature an R32 PC20 rigid foam board insulation core, which is rated for freezer-duty applications down to -20°F to -40°F with a heated frame option. This high R-value reduces compressor run-time and keeps energy costs down compared to older, uninsulated steel doors.

For commercial cold storage, a 26-gauge stucco-embossed steel door with a rigid foam insulation core and heated frame option outperforms standard hollow-metal doors. The steel skin resists dents and corrosion while the foam core and magnetic gaskets stop cold-air leaks, making it the top choice for coolers and freezers.

Standard prehung steel doors are available in widths from 30" to 96" and heights from 76" to 130", covering swing, French, and sliding configurations up to 13'x10' for large-format cold rooms. Custom sizes are also available at no upcharge for oversized, odd-shaped, or non-standard openings.

A plug frame is designed to drop into an existing opening that was originally cut for a plug-style door, common in older walk-in coolers, while a jamb frame attaches to the surrounding wall panel for a more standard retrofit. Both are prehung for faster installation, typically completed in about one hour.

Yes, ELT's prehung steel replacement doors are engineered as drop-in retrofits compatible with any brand, including Kolpak, Amerikooler, Master-Bilt, Nor-Lake, US Cooler, Bally, Polar King, and legacy custom cold-room installations. They install directly over existing wall panels without requiring panel replacement.

Yes, custom-sized steel cooler and freezer doors are manufactured in-house for oversize, odd-shaped, or one-of-a-kind openings at no upcharge. Customers can submit photos or measurements for a same-business-day quote covering dimensions, frame type, and shipping to their location.
