Giambarini Group’s plants in northern Italy must keep zinc baths that rustproof steel and iron parts super-heated around the clock, seven days a week, an energy-intensive process that has grown exponentially more costly as natural gas prices spike.
Methane to create molten zinc that forms a protective coating over high-rise support beams and wrought-iron fences used to take up just 3% of operating costs, but now it's as much as 30%. The family-run company has passed some of the extra cost to customers, but business is uncertain as rising prices for raw materials freezes the construction industry that Giambarini supplies.
