SEE THE
ADVANTAGES
ADVANCED ZERO SPANGLE FINISHING TECHNOLOGY
AM/NS Optima manufacturing uses advanced finishing technology, including a tandem cold rolling mill equipped with auto shape, control, four high skinpass mills and six high tension levellers in combination, to ensure best-in-class flatness tolerances and zero spangle finishing for better end-product manufacturing quality.
HIGHER CORROSION RESISTANCE EXTENDS END-PRODUCT LIFE
The zero-spangle attribute of AM/NS Optima, coupled with skin-passing and uniform zinc coating, ensures superior corrosion resistance and enhances end-product life-expectancy. The optimum chrome passivation is designed to deliver a superior resistance to white rust.
AESTHETICALLY BEAUTIFUL WHEN PURE STEEL NEEDS TO BE SEEN
AM/NS OPTIMA delivers smoother, shiny finishes that are widely preferred in industries where the aesthetic beauty of visible steel is always on display, without the need for coatings or painting.
SUPERIOR DEGREE OF PLASTIC DEFORMATION FOR WORKABILITY
To ensure that AM/NS Optima offers superior mechanical and structural quality, for end-product forming and working utilisation, stringent process control is maintained throughout the manufacturing cycle. This stringent quality control also ensures resilient zinc-coating adhesion during metalworking.
SUPERIOR PAINT ADHESION ACROSS AGGRESSIVE CONDITIONS
AM/NS Optima with its true zero-spangled surface provides better adhesion substrate for end-products with painting requirements, compared to standard or suppressed spangled galvanised steel.
LEAD-FREE FOR A SAFER, MORE ECO-FRIENDLY CHOICE
AM/NS Optima is manufactured lead-free making it RoHS compliant and a safer, more eco-friendly steel choice.
STRONG TECHNICAL AND R&D SUPPORT
Back by deep material expertise and application engineering to support design decisions, process optimisation, and long-term performance.
TIGHT TOLERANCES FOR HIGH PRODUCTION EFFICIENCY
AM/NS Optima is engineered for dimensional consistency that improves line stability, reduces rework, and supports efficient, cost-controlled manufacturing.
