Leviat is proud to announce Rapid-Lok™ Ultimate M (RLU-M), the latest addition to the Rapid-Lok platform of patented engineered corbels designed to provide a permanent, durable, easy-to-install replacement for traditional concrete corbels and welded angles.
MB Rapid-Lok Ultimate M
Safe, easy-to-install alternative to traditional concrete corbels and weld plates
MB Rapid-Lok Ultimate M (RLU-M) is an engineered steel corbel system that provides a permanent, durable, easy-to-install replacement for traditional concrete corbels and welded angles for a variety of applications. The two-step process involves casting the embed plate into a panel or column at the precast plant and later installing the bearing angle onsite.
This process makes RLU-M an easier-to-use alternative to traditional methods and promotes a more streamlined and safer construction process.
Both components are both manufactured from ASTM A572 and A36 steel and feature hot-dipped galvanized (HDG) finish per ASTM A153.
Leviat’s MB Rapid-Lok Ultimate M (RLU-M) is an engineered steel corbel system that provides a permanent, durable, easy-to-install replacement for traditional concrete corbels and welded angles. RLU-M is a safer, more reliable, and more efficient alternative to traditional methods, contributing to a more streamlined and safer construction process.
The RLU-M Embed Plate is cast into the concrete column or panel at the precast plant with the face flush to the wall surface. Once the unit is on-site, the attached void formers are removed from the face of the embed plate to reveal recesses. The RLU-M Bearing Angle ears are then engaged into the recesses of the Embed Plate, securely locking the entire assembly into place without requiring a weld.
The RLU-M Embed Plate and Bearing Angle are both manufactured from ASTM A572 and A36 steel and feature hot-dipped galvanized (HDG) finish per ASTM A153.
Trusted Performance
Rapid-Lok Ultimate M engineered corbels are manufactured in the United States and boast these quality assurances:
- 100% dimensional inspection: Every RLU-M component undergoes comprehensive dimensional checks to ensure compliance to specifications.
- Full traceability: Each product is individually marked, ensuring all quality records are accessible.
- Material & strength testing: Our products undergo rigorous materials testing to guarantee optimal performance, durability and reliability.
Fewer Hurdles
Rapid-Lok Ultimate M eliminates these traditional corbel headaches:
- Labor-intensive operations: Manufacturing concrete corbels is often labor-intensive and costly, requiring the handling of heavy concrete elements. Critical safety measures are essential and add complexity and expense to the process.
- Costly secondary forming: Casting traditional corbels requires specialized equipment, forms and procedures. Concrete mix, curing times, and environmental conditions must be controlled to meet quality metrics and structural standards.
- Inefficient storage and handling: Storing and shipping walls and columns with incorporated corbels is also a challenge. These protruding elements often become obstacles and make the erection process more complex.
