TECHNOLOGY

Production technology of fiberglass armature

Fiberglass reinforcement is based on high-strength fiberglass threads and synthetic resin. Synthetic resins are reinforcement binders and consist of several components that interact with each other in certain volumes and temperatures, as well as in correct and precise manufacturing processes, to create high-quality reinforcements.

Historically, steel rebar is the most commonly used raw material in construction and has had no substitute until now, but now we can offer a compelling replacement for steel.

Two main components are used in production: the reinforcing material itself (roving) and the binder (epoxy resin). The ratio of these components is approximately 80 to 20. In the finished reinforcement, the roving assumes mechanical loads, and the resin acts as a matrix, evenly distributing the loads along the entire length of the rod and protecting the reinforcement from environmental influences.

The production process

The production process of glass fiber reinforcement consists of several stages

01

Stage 1

Each diameter of the fiberglass reinforcement has a certain number of threads. The larger the diameter, the more fiberglass threads are needed. At the beginning of the production process, the fiberglass threads are impregnated with polymer resin.
02

Stage 2

When the fiberglass is completely impregnated, the excess resin is pressed down to a certain percentage and heated in special ovens at a high, variable temperature, creating a chemical process - polymerization.
03

Stage 3

After the polymerization process, the finished armature is carefully cooled with air and water, strengthening its structure. At the end of the process, the finished product up to 10 mm in diameter is wound into rolls, 12, 14, 16, 18, 20 diameter fittings are produced in rods. The length of the rods is adjusted to the customer's wishes.
