Metal accents are essential in achieving a modern industrial theme in kitchens. They can be incorporated through various elements such as cabinet handles, light fixtures, faucets, and appliances. Metal accents add a touch of sophistication and create a visual contrast against other materials like concrete countertops or exposed brick walls. Stainless steel, brass, and copper are popular choices for metal accents in modern industrial kitchens. They not only look stylish but also offer durability and easy maintenance.
