430/2B prepainted stainless steel coil starts with a ferritic 430 substrate-about 16–18% chromium-that stays magnetic, handles mild corrosion well, and keeps cost below austenitic grades. Before coating, the strip is bright-annealed and skin-passed to a smooth 2B finish, so the paint lands on an even, clean base.
On the line we apply a primer, then a polyester or PVDF topcoat, curing each stage so the film survives bending, stamping, and roll forming without lifting at the fold. Finish comes in RAL or custom colors, gloss or matte, and the painted face gets a peelable film before shipment to keep handling marks off the job site. Coil-to-coil consistency is checked on the line-film thickness, adhesion, color-so what ships matches the approved sample.
Applications
430/2B prepainted stainless coil is used mostly indoors, where the color coat does the heavy lifting. Here's where our customers put it:
Refrigerators, microwave ovens and range hoods. Panels face daily wiping and kitchen grease, so the paint film has to stay intact for years - not just look good on the day of delivery.
Elevator cabs and door facings. The 2B finish under the coating gives a smooth, even surface, and the coil holds its flatness through cutting and bending.
Interior wall cladding, ceilings and shop counters in hotels, offices and retail stores, where low maintenance beats a mirror shine.
Water heaters and washing machine cabinets, where humidity and steam are around the clock.
Vending machines, lockers and display cases. 430 is magnetic, which keeps panel fixing simple during installation.
Kitchen splashbacks and signage, for buyers who want the stainless look at a lower cost than 304.

|
Step 3 |
Topcoat coating+baking |
Roll coated colored topcoat, high-temperature setting, endows appearance and strengthens surface protection |
|
Step 4 |
Back paint coating+baking |
Back coated with anti-corrosion paint and cured, double-sided protection to prevent rusting |
|
Step 5 |
Finished product processing |
Full inspection, slitting, and laminating to ensure the integrity of the board surface and complete the production of finished products |
Core Advantages
430/2B prepainted stainless coil starts from a low-nickel ferritic base, delivering stainless-level corrosion resistance and formability at a price less exposed to nickel swings than 304. The 2B surface is smooth and uniform, giving the paint a consistent anchor across the full coil.
The coating acts as a second layer of protection. Primer, topcoat and a backing coat shield both faces of the steel; the topcoat resists UV fading, scratching and impact, and because the paint is applied on the line rather than on site, film thickness is even and edges stay covered. That even film is why the coil can be stamped, bent and deep-drawn without cracking, with T-bend and salt spray results holding from first meter to last.
The result is a stainless surface that keeps its color and corrosion resistance year after year - at a lower cost than equivalent 300-series prepainted coil - for roofing, appliance panels and elevator cladding.
