Standards Reference

Reference standards by category

Standards listed are for engineering and procurement reference only, never certificates held by MutualMetal. Applicable standards, material grades and documentation are confirmed per product and project.

Perforated Metal
Headline product and application reference standards
GB (Chinese National)
ASTM (International)

No single universal product standard for general-purpose perforated metal; ISO 7805/10630, GB/T 6003.2 and ASTM E323 apply to industrial screens and test sieves. Pattern and margins are custom-specified per drawing.

ScopeConfirmed per project
Expanded Metal
Headline product and application reference standards
GB (Chinese National)
ASTM (International)
ANSI / NAAMM / EMMA
EN / DIN (Europe / Germany)
