Fiberglass rebar
standards

This section contains some regulatory documents of various countries on the design of structures using fiberglass rebar and requirements for it. Application regulations are an important part of the development of the composite industry in countries. Documents make it possible to form a market for innovative material, obtain an economic benefit from the properties of the material, and increase the life cycle of buildings, structures and structures.
