Signage is an essential tool in every industry to promote their business and brand. It affects the psychology of human minds by its vibrant colors, visuals, and graphics. For instance, if a person sees the yellow color of the letter M the person's mind signals that it is a symbol of Mcdonald's. It is because wherever the Mcdonald's food chain is present, there always will be this huge letter in front of the store. It is the usage of sign boards, and people recognize instantly. Hence, metal letters Chennai plays a vital role in promoting the business to new heights. However, with the help of technology and advancements, there are numerous sign boards in the market. One of the prominent and helpful sign boards is metal signage. The sign board makers use bronze, brass, aluminium, and stainless steel in the metal signage. Aluminium and stainless steel are the commonly used metals in the industry. Hence, in this post, listed below are some pros and cons of the aluminium and stainless steel sign boards.

 

Strength:

 

The prime thing to look into in metal signage is the strength and weight ratio of the metal. Metals naturally have higher tensile strength and weight ratio compared to LED sign boards in Chennai. The tensile strength of aluminium metal is 505 MPa, and stainless steel is 276 MPa. Hence, aluminum has high tensile strength compared to stainless steel. Therefore, aluminum can withstand harsh weather conditions.

 

Corrosion:

 

Aluminium and stainless steel metals are resistant to oxidation and corrosion. The aluminium metal can create a passivation layer and prevent the metal from rusting. It comes with different alloys such as 5052 and 6061. The aluminum alloy with grade 5052 is the marine grade and superior in resistance to corrosion to the aluminium alloy 6061 grade. Stainless steel has chromium content and is resistant to corrosion naturally. It also comes with alloys of grade 304 and 316, and 316 stainless steel is expensive compared to aluminium. Hence, aluminium is an excellent option in terms of corrosion resistance.

 

Cost:

 

Stainless steel is more expensive compared to aluminium signage. The density of aluminum and stainless steel is 2.81gcm and 8gcm, respectively. Hence, aluminium is one-third dense of stainless steel metal, and stainless steel costs around 30% of the price compared to aluminium. Hence, aluminium is a cost-effective option.

 

Hence, sign board manufacturers in Chennai use aluminium in the metal signage compared to stainless steel. Therefore, it is wise to choose aluminium sign boards for the store and last for a long time.
