Forms for concrete made of fiberglass are characterized by increased strength, they are resistant to temperature changes and relatively inexpensive. Although more expensive than forms made of ABC and PVC plastic.
They include fiberglass and epoxy-polymer resins and are available in thickness from 5 mm. It is the composition that makes the fiberglass forms the toughest. In addition, they are additionally reinforced with metal frames, which makes them ideal for the production of Euro fences using the instant ejection method. They are dried on special stretcher-racks. This makes it possible to produce up to 20 products in one form per day with experience.
They are also used for the production of tombstones, monuments and various small architectural forms. Such as flowerpots, garden sculptures and other decor.
However, they are not suitable for the manufacture of paving slabs, since the formwork method is not applicable to them. Another feature of fiberglass concrete molds is the impossibility to paint the concrete mass. The product is painted after production or after installation.
Along with the forms made of ABS plastic, this is one of the most demanded types of forms for concrete on the building materials market.
