AASHTO M 336M/M 336-20涵盖了用于混凝土加固的热轧钢筋制成的碳钢丝和焊接钢丝加固。钢丝为冷加工、拉拔或轧制、普通（非变形、拉拔或镀锌）或变形钢丝。焊接钢丝加固由普通钢丝或变形钢丝或普通钢丝和变形钢丝的组合制成。注:混凝土钢筋的焊接金属丝由不同的术语描述:焊接金属丝织物（WWF）、织物和网格。钢筋行业更喜欢术语焊接钢筋（WWR），因为它更能代表正在制造的产品范围。因此，在本规范和相关规范中，术语焊接钢丝网已替换为术语焊接钢筋。本规范适用于以国际单位制（M 336M）或英寸-磅单位（M 336）为单位的订单。

AASHTO M 336M/M 336-20 covers carbon-steel wire and welded wire reinforcement produced from hot-rolled rod to be used for the reinforcement of concrete. The steel wire is cold-worked, drawn or rolled, plain (non-deformed, as-drawn, or galvanized), or deformed. Welded wire reinforcement is made from plain or deformed wire, or a combination of plain and deformed wire.Note: Welded wire for concrete reinforcement has been described by various terms: welded wire fabric (WWF), fabric, and mesh. The wire reinforcement industry prefers the term welded wire reinforcement (WWR) as being more representative of the range of products being manufactured. Therefore, the term welded wire fabric has been replaced with the term welded wire reinforcement in this specification and in related specifications.This specification is applicable for orders in either SI units (M 336M) or in inch-pound units (M 336).
