Vďaka redline sa okamžite dozviete o:
Ušetrite si čas aj starosti!
Vďaka Redline už nebudete musieť strácať čas zisťovaním, čo sa v novej norme zmenilo. Redline Vám ušetrí čas a zaručí, že sa o zmenách v norme dozviete.
Cena
Ak si zvolíte možnosť "Platná norma + Redline", potom dostanete oba dokumenty! A čo je najlepšie, cena Platné normy + Redline je len o niečo málo vyššia ako cena samostatnej platné normy.

This specification covers the requirements for zinc coatings applied by the electrolytic process to any grade of hot-rolled or cold-rolled steel sheets for applications requiring designation of the coating mass on each surface. Coating application shall be done on one or both surfaces with equal or differential coating masses and similar levels of corrosion protection, and shall have no effect on the base metal mechanical properties. The coated sheets may be available as commercial steel (CS), drawing steel (DS), deep drawing steel (DDS), extra-deep drawing steel (EDDS), structural steel (SS), high-strength low-alloy steel (HSLAS), high-strength low-alloy steel with improved formability (HSLAS-F), solution-hardened steel (SHS), or bake-hardenable steel (BHS). Coatings shall be designated accordingly, and shall undergo test methods such as weigh-strip-weigh method, nondestructive X-ray fluorescence measurement, and Coulometric method. Accordingly, individual coating designations should conform to coating weight, mass per surface, and thickness requirements.
