Stonebridge Architectural Ironmongery

Suffolk Latch Company is pleased to offer the Stonebridge Architectural Ironmongery collection. Manufactured from forged steel, this range combines modern engineering techniques with traditional manufacturing methods to produce consistent, high-quality hardware for residential and commercial projects.

Stonebridge Ironmongery is a family-owned business based in County Durham and forms part of DJH Group Ltd.

Engineered Hardware

Traditional hand-forged ironmongery is valued for its individual character, with slight variations from one piece to another. While this is often desirable for period properties, some projects require consistent dimensions and precise manufacturing tolerances.

Stonebridge products are engineered to deliver accurate dimensions and fixing centres, making them well suited to new-build homes, renovations and larger installation projects.

• Each product begins as a hand sketch before being developed using modern CAD software.
• Precision tooling is produced before heated steel is forged under high pressure.
• Components are assembled using a combination of automated manufacturing and skilled hand finishing.

Accurate tooling provides consistent measurements throughout the range, helping installers achieve a professional finish while making replacement and specification simpler across larger projects.

Armor-Coat® Protective Finish

Standard hand-forged ironmongery finished in beeswax or pewter is generally intended for internal use because these finishes offer limited protection against weathering.

Stonebridge products are protected with the proprietary Armor-Coat® finish, developed to provide excellent resistance to corrosion and UV exposure.

• Exclusive Armor-Coat® protective coating.
• Tested to BS EN 1670:2007 Grade 5.
• Provides one of the highest levels of corrosion resistance available for steel-based architectural hardware.
• Offers long-lasting UV protection and helps maintain the finish over time.

Accoya® Tested

Stonebridge hand-forged hardware has also been tested for use with Accoya® timber and other acidic hardwoods. Accoya® is widely specified for external joinery because of its stability and durability.
