1. rebar coupler for our building a. It's a parallel thread mechanical splicing system designed for the connection of reinforcement steel bars from Φ12~Φ50b. material:#45 carbon steel 2. characteristic of product a. Thread angle:60°,75° b. Designed and manufactured in compliance with ACI318, JGJ107, UBC 1997, BS8110, NF35-20-1, DIN1045, ISO/WD 15835c. Easy to operate and maintain, high production efficiency and fast installation, no need of skilled techniciansd. Several types of splices, which could be suitable for rebar splicing when the rebar cage or the bending rebar is usede. The coupler could be produced in advance without influencing the construction periodf. with low cost of purchasing, maintaining and repairing.g. Couplers and threaded bars are protected by plastic caph. material origin traceability and production batchi. Manufactured under strict quality assurance plan ISO 9001 3. Benefits: a. Practical alternative to lap splicingb. Solves rebar congestion problemsc. Shortens construction periodd. Reduces steel wastage 4.
