MDF is a wood based composite material that draws on the usage of wood fibres, rather than particles or veneers to produce board or sheet products. It is typically made as a board type product, though it's use in mouldings and increasing use as a structural product will see beam type products proliferate. It is replacing the use of particleboard in uses such as furniture manufacture, cabinet making, joinery, craft work and flooring. Its advantages include high strengths (MOR of 80 MPa and MOE of 3000 MPa), ease of machining, good weathering properties, and the ability to be made from a wide variety of fibrous products.

Acrylic

Poly(methyl methacrylate) (PMMA) is a transparent thermoplastic, often used as a lightweight or shatter-resistant alternative to glass. It is sometimes called acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate.

PMMA is a versatile material and has been used in a wide range of fields and applications, for examples: transparent glass substitute, daylight redirection, medical technologies and implants, artistic and aesthetic uses, etc.

Sheets of PMMA are commonly used in the sign industry to make flat cut out letters in thicknesses typically varying from 3 to 25 millimeters (0.1 to 1.0 in). These letters may be used alone to represent a company's name and/or logo, or they may be a component of channel letters which are neon or LED illuminated. Acrylic's attractiveness, durability and resistance to warping make it an ideal interior and exterior sign material. Acrylic is also used extensively throughout the sign industry as a component of wall signs where it may be a backplate, painted on the surface or the backside, a faceplate with additional raised lettering or even photographic images printed directly to it, or a spacer to separate sign components. One of the most popular sheets is a non-glare, translucent which is sold in 1.6 millimeters (0.06 in) or 3 millimeters (0.12 in) in thicknesses.

Metal

Sheet Metal (Stainless Steel)
Grade 304 offers good corrosion resistance while maintaining formability and weldability.
Grade 316 offers more corrosion resistance and strength at elevated temperatures than 304. It is commonly used for pumps, valves, chemical equipment, and marine applications.

Finishes:

  1. Bright cold rolled, annealed, and pickled.
  2. Grained 100-120 grit
  3. Grained 150-180 grit

Metal protection:
Galvanization (Zinc coatings) is the process of applying a protective zinc coating to steel or iron, in order to prevent rusting. Common methods in current use are hot-dip galvanization and Sherardizing.

LED

A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, and faster switching, which are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. Also, LEDs are used in applications as diverse as aviation lighting, automotive lighting, advertising, general lighting, and traffic signals.

Tube Light

Different Sizes are available such as T2, T4 and T5 (T5 with 14W, 20W, 28W and 35W)

Although it is cheaper than LEDs, it's lifetime is relatively shorter and the frequency of failure is higher than LEDs.
