The Central Testing Hub
At United Brothers, we don’t rely on assumptions; we rely on data. Our factory houses a comprehensive central laboratory that acts as an independent regulatory body, equipped with the latest digital measuring devices and periodic calibration tools to ensure every product complies with global codes (ASTM & EN).
Wire Testing Protocols
Drawn and galvanized wires undergo a series of physical and chemical tests to ensure subsequent forming efficiency.
Tensile Strength
(UTS) Using advanced hydraulic testers, we measure maximum force and Yield Point to ensure no permanent deformation.
Torsion Test
Twisting the wire to test metal homogeneity; zero microscopic cracks guarantee complex spring forming efficiency.
Wrapping Test
Testing zinc layer adhesion around a mandrel, ensuring no peeling or cracking occurs during bending.
Digital Precision
Monitoring Roundness and diameter Tolerance with 0.01 mm precision, preventing machine jams.
Spring & Frame Durability
Because the spring is the heart of the mattress, we test its life cycle before it leaves our facility.
Fatigue & Dynamic Loading
Simulating 10 years of use by compressing units thousands of times. We measure Height Loss against global standards.
Tempering Verification
Examining samples post-heat treatment to remove mechanical stresses, granting superior Recovery Memory.
Acoustic Testing
Inspecting connection points for a Squeak-free build, providing a completely silent sleep experience.
Environmental Resistance
Ensuring durability in the most challenging conditions
Salt Spray Chamber
Simulating coastal climates to measure zinc oxidation resistance before rust appears.
Mill Test Certificate (MTC)
Every shipment includes technical analysis documented by our lab as tangible proof of quality.
Global Certifications & Accreditations
Quality at United Brothers is a daily, documented methodology accredited by major international regulatory bodies.
The ISO Trinity
ISO 9001:2015 (Quality Management): Ensures all workflows—from procurement to after-sales—follow a global system that guarantees quality consistency
ISO 14001:2015 (Environmental Management): Reflects our commitment to sustainability, carbon footprint reduction, and resource efficiency.
ISO 45001:2018 (Occupational Health & Safety): Ensures a safe work environment for our employees, guaranteeing uninterrupted production flow.
Compliance with Global Engineering Codes
EN (European Standards)
Application of European standards for mattress and furniture spring wires (e.g., EN 10270), facilitating confident access to European markets.
ASTM (American Standards)
Strict adherence to the American Society for Testing and Materials for wire diameters, raw material hardness, and tensile strength.
International Galvanization Standards
Our galvanized wires meet global hot-dip standards for zinc density and oxidation resistance.
R&D Center
The R&D department is the intellectual engine of our institution, where metallurgy meets manufacturing technology.
Metallurgical Innovation
Finding the 'Perfect Formula' for strength and formability.
Ergonomic Engineering
Developing Multi-Zone Units based on pressure distribution.
Eco-Innovation
Drawing techniques that minimize raw material waste.
Tailor-Made Solutions
Prototyping for out-of-the-box custom specifications.
