Reinforcement couplers are mechanical devices used to join reinforcing bars in construction, providing a reliable alternative to lap splicing. Quality testing for couplers ensures their tensile strength, slip resistance, and fatigue performance to maintain the structural integrity of reinforced concrete structures.
Structural steel is a key material in construction, valued for its high strength and versatility. Quality testing evaluates mechanical properties such as tensile strength, yield strength, elongation, and impact resistance. These tests ensure that the steel meets safety and performance standards for use in load-bearing structures.
High-strength deformed steel bars and wires are used for reinforcing concrete structures, offering superior tensile strength and bonding characteristics. Testing includes tensile strength, elongation, and bend/rebend tests to ensure compliance with design specifications and durability requirements.
