Heavy Duty Commercial Doors and Solutions

This page does not specify a hollow metal door thickness, as ELT Custom Coolers' product line consists of insulated prehung swing and sliding doors designed for walk-in coolers and freezers rather than standard hollow metal doors. Instead, door dimensions are given as overall sizes — swing doors from 30" to 60" wide and 76" to 84" tall, and sliding doors from 36"x78" up to 12'x12' — with custom sizing available upon request from their product experts.

ELT Custom Coolers offers several types of heavy duty commercial doors for walk-in coolers and freezers: prehung swing replacement doors, sliding doors (manual or electric), and complete walk-in box units. Frame configurations include standard/plug frames, heated jamb frames for frost prevention, and jamb sandwich frames with headers. Strip curtain accessories like the Kason 402 Easimount are also available as secondary thermal barriers for high-traffic doorways.

Commercial walk-in cooler and freezer doors range from approximately $1,250 to $12,500+ depending on door type, size, and frame configuration. Swing replacement doors start around $1,250, while large-format sliding freezer doors (up to 96"x120") can exceed $12,500. Equipment financing is available through MyCloudFunding for flexible ownership options.

A prehung walk-in cooler door arrives pre-assembled with its frame — either a standard frame or plug frame — and is designed as a true drop-in replacement. No on-site fabrication is required. You simply mount the unit in the existing opening, which significantly reduces installation time and labor costs.

A heated jamb or heated frame is an electric resistance element embedded in the door frame that prevents frost and ice buildup at the door opening. This is critical for walk-in freezer applications where temperature differentials cause door-stick, condensation, and ice accumulation. ELT offers heated frame options on select swing and sliding freezer door models.

Yes. Every door from ELT Custom Coolers meets UL certification and DOE 2017 energy standards, and products are also NSF Approved. These certifications ensure regulatory compliance, food safety requirements are met, and reduced compressor run-time for lower utility costs across your cold storage operation.

Sliding doors are preferred for high-traffic or forklift-access applications, such as food processing plants, distribution warehouses, and supermarket backrooms where pallet jacks or forklifts need pass-through clearance. Swing doors are better suited for standard-access openings in restaurants, commercial kitchens, and smaller cold storage units. ELT offers both manual and electric sliding door options.
