Protrim N is a line of stainless steel external corner profiles with a slightly rounded shape. The special steel alloys used make Protrim N profiles perfect for use in a variety of settings: AISI 304 stainless steel is ideal for food production sites, kitchens and hospitals, while AISI 316 stainless steel - thanks to its resistance to the main chemical and atmospheric agents, chlorine and salt water - is recommended for swimming pools, spas and seaside areas.
