Wire Reinforcement Institute

Our mission is to promote the specification and usage of welded wire reinforcement (WWR) through the provision of a diverse base of design and construction-related resources.

Welded Wire Reinforcement (WWR)

Welded wire reinforcement is steel reinforcement that can be used in virtually any structural application across the full range of concrete construction. Today, concrete structures across the world are being successfully and economically reinforced with high-strength, customizable welded wire reinforcement.

In concrete, welded wire reinforcement speeds construction, exhibits exceptional tolerance control in structural placement, and is recognized by industry codes and design standards as a reinforcement that fits all manner of structural reinforcement applications.
