The first generation hollow plastic product construction template
Inside are round holes and square holes. Encountered too many problems in actual use, the total weight is heavy, it is easy to enter the cement mortar, and the compressive strength and flexibility are insufficient.
Second generation V shape
Only a few features have been changed.
Three generation X type
The compressive strength is better than before, and the compressive strength and flexibility are improved. However, the reinforcing ribs will be partially broken during the cooling and shaping, and the slurry running is not fully treated. The gap between the two sides is large, and it cannot be fully used on the construction site.
Four generations of checkered
After a decade of technological upgrading, various basic parameters have been improved. However, it is easy to cause large quantities of slag when cutting, and the color tone is single. The color is centered on black, and black is easily deformed in high temperature. But if the black is replaced with other colors, the compressive strength of the building template will not reach.
Five generations two machines co-extrude small squares
Nanotechnology polymer raw materials are used, and the two-machine co-extrusion technology is used. The surface is changed to milky white or dark gray, and the black in the middle is closely combined. The new building formwork not only solves the problem of thermal expansion and contraction but also reduces costs.
ZMADTO Plywood Co.Ltd is focus on construction plywood & wood formwork product.
