Prefabricated buildings generally use prefabricated beams.

Reinforced concrete precast beam, prestressed concrete precast beam.

1. Reinforced concrete precast beam: composed of steel bars and concrete, with stable structure, high strength and convenient construction. The production of precast beam workshop can control the quality and improve the production efficiency.

2. Pre-stressed concrete precast beam: Pre-stressed concrete precast beam has been pre-stressed in the production process, which has higher strength and stability and can be used in long-span situations.
