304 Stainless Steel Double Swing Traffic Free Door For Food Processing Kitchen

This heavy‑duty stainless‑steel free swing door is specially engineered for high‑frequency passage in food‑grade industrial environments. Equipped with double‑action auto‑return hinges, door leaves swing 180° in both directions and reset automatically after impact from trolleys and transport carts. SUS304 brushed stainless‑steel surface is easy to wash and sanitize, paired with heavy‑duty PE anti‑collision bumper plate to resist daily collision damage. Seamless frame construction supports hygienic cleaning, widely adopted in food processing workshops, central kitchens and supermarket back‑store logistics aisles. OEM custom sizes, vision window and hardware options are available for global commercial and industrial projects.

Stainless‑steel free traffic door, also known as impact swing door, eliminates manual door‑opening operation for staff carrying goods. Different from ordinary hinged doors, it focuses on high‑cycle durability and sanitary performance. Double‑leaf structure fits wide logistics channels; surface stainless‑steel material resists moisture, detergent corrosion and dirt accumulation. It reduces workflow bottlenecks for busy production and catering facilities.

Door face: SUS304 brushed stainless‑steel sheet; internal high‑density honeycomb non‑water‑absorbing core; full‑welded stainless‑steel frame. Top mounted heavy‑duty double‑action self‑return hinge with built‑in bearing. Bottom fitted with thick PE anti‑collision bumper plate. Optional polycarbonate transparent vision window. Rubber sealing strip around frame for dust and noise reduction.

Confirm wall opening dimension and wall load‑bearing capacity. Door frame can be embedded or surface‑mounted. Reinforce wall structure for large‑size door leaves. All mounting accessories are supplied; customers can arrange local construction team for installation. Provide technical drawing reference.

Clean stainless‑steel surface with neutral cleaning agent, avoid strong corrosive solvent. Check hinge fastening screws and bumper plate fixation every 6‑12 months. Do not strike hinge position with heavy objects. Replace worn bumper plate when obvious cracking appears.
