Challenge

In Thailand, the combination of air-conditioning and humidity places great demands on the materials. It is critical that the stainless steel provides the necessary corrosion resistance and good welding.

Solution

Outokumpu Core 4622 offered perfect solution thanks to its good weldability and corrosion-resistance.

Outokumpu Core 4622 shines from 7-Eleven

When Noppol Chuklin, Managing Director of Thailand’s RBS Group, shops for new materials, he leaves no room for compromise. A major supplier of display equipment and interior decoration for the country’s retailers, his company has built its brand reputation on providing only high-quality solutions.

In 2014, after winning a bid to outfit about 6,000 of Thailand’s 7-Eleven convenience stores, Khun Noppol realized that the grade 304 stainless steel he was buying wasn’t up to his quality needs and he began looking for alternatives. That’s when Khun Noppol contacted Outokumpu’s Bangkok office and learned about a new grade, Outokumpu Core 4622.

 

Convinced by high qualities

“For the equipment RBS was supplying to 7-Eleven, it was critical that the stainless steel would offer the needed corrosion resistance with good weldability,” says Khun Noppol.

Naturally, cost was also a factor. As it happened, the price was competitive with 304, and after hearing a presentation on Core 4622, Khun Noppol was convinced enough to try it out with a test order.

RBS received its first container of Core 4622. The material came in the form of sheets, which RBS cut and welded into the products it needed – in this case, the metal frames for light boxes, the illuminated signs that appear outside the 7-Eleven outlets.

“So far, the material has lived up to every one of our requirements. However, we did make some adjustments in our manufacturing process to compensate for the higher strength of the material,” Khun Noppol says.

 

Air conditioning conquers moisture

Based on the success of the light box production, Khun Noppol would nowlike to expand his use of Core 4622 to other equipment, beginning with counter tops.

Outokumpu’s Senior sales and marketing manager S.E.A., Koh Tiah Ann, points out that the anti-corrosion properties of Core 4622 make it an ideal option for interior elements in a convenience store like 7-Eleven.

“In an environment where humid weather, air conditioners and refrigerator units mix, moisture – and the potential for unhygienic rust – is ever-present,” says Koh.

Even retailers who don’t sell food, he says, would benefit from Core 4622’s corrosion resistance because pretty much every shop in Thailand has the same issues with air conditioning and moisture.
