Decorated sheets are generally known as ‘Perforated Sheets’ or perforated screen/sheet metal/plate. 316L is the low-carbon, standard molybdenum-bearing grade from the austenitic stainless steel group. It is used to manufacture decorated sheets as it has excellent toughness, high resistance to the crevice, and pitting corrosion.
The use of perforated materials in design is limited due to a lack of reliable strength and stiffness characteristics. The 316L decorated sheets are available in wide specifications and in different sizes, shapes, thicknesses, and other variables. The decorated sheet can be surface treated according to our requirements viz. Galvanizing, Anodizing, Reflective shine finish, etc.
CHEMICAL COMPOSITION OF 316L
- Chromium – 16.00-18.00%
- Nickel – 10.00-14.00%
- Molybdenum – 2.00-3.00%
- Carbon – 0.035% max.
- Manganese – 2.0% max.
- Silicon – 1.0% max.
- Phosphorous – 0.045% max.
- Sulfur – 0.030% max.
DECORATIVE PATTERNS
In a decorated sheet generally holes are punched to create designs/patterns. The holes in straight pattern are aligned horizontally or vertically. The holes in a staggered design are also staggered evenly between rows. They can be of various shapes such as round, square, hexagon, etc.
FUNCTIONAL CAPABILITIES OF DECORATED SHEET
- Acoustical Capabilities – Transparent to sound & Absorbs certain sound frequencies
- Radiation Containment – EMI/RFI & Microwaves
- Ventilation – Permits airflow
- Aesthetics – Control of Sound, Lighting, Ventilation, Design
USES OF DECORATED SHEET:-
Functions:
- To cover, enclose, divide, decorate, ventilate.
- To control the passage of air, gases, sounds, etc.
- To separate solids
- To filter liquids
- Create various lighting effects
- To minimize weight
Applications:
- Architectural Components – Walls, Floors, Ceilings, Grills, Dividers, etc.
- Lighting Components – Perforated metal light fixtures offer a solution that combines preferred aesthetics with usability. E.g. linear lighting, diffusers, etc.
- Acoustic Components – Perforated metal is an important component in the construction of noise control systems and noise control products. It can also be used as a resonant sound absorber, which reduces or eliminates sounds in a specific frequency range. E.g. speaker grilles, sound rooms, concert halls, etc.
- Industrial Machinery – It is deemed ideal to protect expensive and delicate equipment’s hence, it is mainly used for the cabinetry business. It is also used as a noise-reducing enclosure for Power generating machines. E.g. electronic enclosures, machine guard grilles, computer equipment, etc.
- Appliances – Perforated metal aids in the proper operation of appliances by ensuring the flow of light and air, holding filtration substrates, protecting the unit, preventing overheating, eliminating debris clogs, and reducing moisture formation. E.g. refrigerators, washers, dryers, dishwashers, etc.
- Transportation – The products made from perforated sheets used in the transport industry are ventilation screens, Seat rails, Grilles, Heat shields, etc.
