Expanded metal from Fratelli Mariani is a universal solution for facades, fences, architectural elements and industrial applications. The combination of high rigidity with low weight, stable cell geometry and a wide variety of decorative designs allows to achieve both technical reliability and a distinctive visual effect. The material is available in carbon steel, stainless steel, aluminum and other alloys; various surface treatments and additional technological operations (protective coatings, painting, hot-dip galvanizing) are possible, which simplifies integration into projects with increased requirements for durability and operation.

Standard geometries and sizes vary from micro-grids with a cell pitch of approximately 0.75 × 0.45 mm to larger blocks, such as 20 × 15 mm; material thicknesses and total sheet thickness are also available in a wide range for different loads and design requirements. Sheet sizes usually start from a few hundred millimeters and reach panels of about 1000 × 2000 mm or 1250 × 2500 mm depending on the type and design. These parameters allow you to select expanded metal for both small decorative elements and large facade systems.

Fratelli Mariani guarantees serial availability of a wide range and the possibility of custom manufacturing, which gives an advantage for urgent projects or when non-standard sizes and configurations are required. This makes the material a practical choice for architects and contractors who value the combination of functionality, aesthetics and operational logistics.

Sheet and roll sizes

The dimensions of the finished products vary depending on the material and the type of cell:

• Standard sheets: Usually 1000 x 2000 mm, 1250 x 2500 mm or 1500 x 3000 mm.
• Maximum width (Hmax): For most architectural series (e.g. Raval, Montmartre) the maximum sheet width is 1500 mm, but for some models it can reach 2500–3000 mm.
• Length: Can be almost any to order (in rolls or cards), but is limited by ease of transportation and weight.
