SMC Waffle Board are steel-concrete structures made with glass fiber reinforced plastic (epoxy glass fiber reinforced plastic) as templates. After pouring, the template is used as the bottom mold to meet the cleanliness requirements of general electronics factories. SMC waffle board is a structural material, but in order to improve certain properties, oriented SMC waffle boards can also be produced. Suitable for construction, transportation and packaging industries.
Characteristics of SMC Waffle Board
1. Using SMC waffle boards as templates can ensure accurate hole generation, high floor flatness and excellent flatness. The bottom edge and wall of the holes can be immediately used as decorative design layers.
2. It is produced and processed in a processing plant and can be installed immediately on the construction site. Easy to install, simple and practical to operate. Construction is faster and more reliable.
3. Choosing SMC waffle boards to replace the epoxy resin ceiling architectural coatings required in the purification workshop not only saves raw materials, but also saves the construction time of epoxy resin ceilings.
4. SMC waffle board solves the problems of large plate thickness, large dead weight of the bottom plate, and concentrated hole spacing.
5. The appearance and construction quality have been significantly improved. After the construction of the project, the roof was used as the base to eliminate common product quality problems such as cracking, peeling, and exposure of the roof of general concrete structures, saving costs. as well as the cost of maintenance and post-maintenance, and has an excellent appearance.
Product advantages
The four-direction facade is designed with a large arc shape, which greatly improves its pressure resistance and prevents product deformation during pouring.
There are multiple high-width reinforcing ribs from top to bottom on the 4-direction facade to improve the pressure resistance and fix them more firmly in the concrete.
