Crafted from premium grade stainless steel, this handle set delivers exceptional resistance to corrosion, wear, and everyday use while maintaining a sleek, modern appearance. Engineered specifically for interior applications where both functionality and aesthetics matter, the handle features a reinforced structure that withstands frequent operation without loosening or performance degradation. Its substantial feel and balanced weight provide satisfying operation, while the variety of finish options ensure compatibility with diverse interior design styles. Whether installed in residential or commercial settings, this heavy-duty handle set offers the perfect combination of durability, comfort, and visual appeal for interior doors.
The handle and rosette are precision-cast from 304 stainless steel, an alloy containing 18% chromium and 8% nickel that provides superior corrosion resistance compared to standard steel. This material offers a tensile strength of ≥515 MPa and excellent resistance to rust, making it suitable for humid indoor environments like bathrooms and kitchens. The solid construction eliminates hollow spots that can create noise or weakness in lesser quality handles.
Engineered for heavy use, the handle features a 12mm diameter grip section with internal ribbing that strengthens the structure without adding excessive weight. The mounting system utilizes M5 stainless steel screws that secure into reinforced bosses within the rosette, distributing stress evenly across the door surface. A 3mm thick mounting plate ensures stable attachment, preventing wobble or loosening even after thousands of operations.
The handle's contour is meticulously engineered to fit natural hand positions, reducing grip fatigue during daily use. It features a 120mm grip length and 65mm projection from the door surface, providing comfortable leverage without protruding excessively into room spaces. The smooth, rounded edges eliminate sharp contact points, enhancing safety while maintaining a refined appearance.
Available in satin brushed and polished finishes, both achieved through mechanical processes rather than plating, ensuring the finish penetrates the surface and resists wear. The satin finish features a 0.8μm surface roughness that hides fingerprints and minor scratches, while the polished finish provides a mirror-like appearance with ≥800 gloss units reflectivity. Both finishes are non-porous, making them easy to clean and sanitize.
The Stainless Steel Heavy Duty Interior Door Handle is ideally suited for high-traffic indoor environments requiring durable, attractive door hardware. It excels in residential applications including entryways, hallways, and bedrooms where family members frequently use doors. The handle is perfect for commercial settings such as offices, schools, and healthcare facilities where equipment must withstand constant use. Its corrosion resistance makes it suitable for bathroom doors, kitchen pantry doors, and laundry room entrances where humidity levels are higher. The handle complements various interior styles from modern minimalist to transitional designs, integrating seamlessly with both contemporary and classic decor. It fits standard door preparations, making it suitable for new construction or retrofit projects on wooden, composite, and hollow-core interior doors.
The Stainless Steel Heavy Duty Interior Door Handle is designed to fit standard interior door thicknesses ranging from 32mm to 45mm. The included adjustable spindle can be cut to length for precise fitting, and extension kits are available for doors up to 60mm thick if needed for specialized applications.
The 304 stainless steel construction contains chromium that forms an invisible protective oxide layer on the surface, preventing rust and corrosion. This passive layer self-heals if scratched, maintaining protection even with regular use. This makes the handle particularly suitable for bathrooms, kitchens, and basements where humidity levels are higher than other indoor spaces.
Yes, when paired with appropriate fire-rated locksets, this handle is suitable for use on 30-minute and 60-minute fire-rated interior doors. The stainless steel construction maintains structural integrity at elevated temperatures, and the mounting system meets fire code requirements for secure attachment during emergency conditions.
Unlike standard handles that often use hollow construction or lower-grade materials, this heavy-duty model features solid 304 stainless steel construction with reinforced mounting points. It's designed to withstand over 100,000 operations without loosening or performance degradation, making it approximately three times more durable than standard interior handles.
Maintenance is minimal. Simply wipe the handle with a soft cloth and mild detergent as needed to remove dirt and fingerprints. Avoid abrasive cleaners or steel wool that could damage the finish. For optimal performance, check the mounting screws annually and tighten if necessary—though the reinforced mounting system typically prevents loosening even with heavy use.
