About Us

Our doors meet exacting standards for walk-in coolers and freezers, commercial cold storage, as well as scientific chambers and many other applications. Over 40 years of experience is built into every door which is why walk-in cooler and freezer manufacturers use R⁺ doors as original equipment on their walk-in coolers and freezers.

R⁺ Doors is a leading manufacturer of high-quality cold storage doors engineered for walk-in coolers, freezers, refrigerated warehouses, food processing facilities, and other temperature-controlled environments. With more than 40 years of industry experience, R-Plus combines proven craftsmanship with innovative engineering to provide dependable door solutions for demanding commercial and industrial applications.

The R⁺ product line includes swing doors, horizontal sliding doors, bi-parting doors, vertical lift doors, traffic doors, replacement glass doors, and specialized replacement and retrofit solutions. These products serve a wide variety of industries, including food service, supermarkets, convenience stores, warehousing, health care, scientific facilities, hospitality, schools, and industrial operations.

R⁺ places particular emphasis on durability, energy efficiency, and ease of installation and maintenance. Its cold storage doors incorporate features such as foamed-in-place polyurethane insulation, heavy-duty hardware, replaceable gaskets, and application-specific sealing systems. The company has also developed adjustable swing-door hinges designed to compensate for installation variances and settling that can otherwise interfere with an energy-efficient seal.

For existing facilities, R⁺ offers replacement and retrofit doors that can be installed into older openings or incorporated into existing insulated panels. These solutions can help facilities modernize damaged or aging door systems without requiring complete replacement of the surrounding structure.

From standard walk-in cooler entrances to large powered sliding and vertical-lift systems, R⁺ focuses on providing reliable cold storage solutions backed by knowledgeable sales and support. With locations serving customers across the United States, the company supports projects from initial product selection and quoting through installation and long-term operation.
