Marco de normas
Marco de normas
Para cumplir requisitos de importación, diseño estructural y compras industriales, trabajamos con tolerancias y ensayos de cuatro sistemas principales.
ASTM / ASME
American Standards covering chemical limits and mechanical tensile configurations.
EN / DIN
European standards focusing on Charpy impact codes and cold toughness parameters.
JIS
Japanese standards defining dimensions and coatings of cold-rolled high-precision flats.
API
American Petroleum Institute specifications for demanding pipeline transfers.
