The main types of LED Letters' steel structures on the roof are divided into three types: steel structure, stainless steel structure, and aluminum alloy structure. First of all, it is necessary to clarify the nature of the structure of the billboard equipment, such as wall, curtain wall, steel structure, roofing, etc., and then calculate the bearing capacity of the equipment surface according to the steel structure planning standard, calculate the steel structure usage and the number of support points. The following is a highlight of the characteristics of the roof-mounted illuminated LED letters' steel structure from Smart Sign, and the attention of problems.
Steel structure: Generally speaking, the steel structure refers to the steel structure without any special explanation. The first is to use angle steel, rectangular steel, I-beam or channel steel. This kind of structural strength is large, the bearing capacity is strong, and the wind resistance level is high. It is a structural method that is widely used and cost-effective when installing the roof lighting letter signs.
Stainless steel structure: The price of stainless steel structure is more expensive than that of steel structure. The strength and wind resistance are not so good compared with steel structure. The advantage is more beautiful, smoother than steel structure. This method is generally used in places where the requirements are relatively high and where the wind resistance is not critical.
Aluminum alloy structure: This structure and stainless steel structure are similar in nature, high in cost and poor in strength, and characterized by convenient construction and beauty. It is also generally used in a position where the requirements are relatively high and the wind and compression resistance level is low.
Normally, the roof-illuminated signage less than 2 meters can be directly welded with 40mm*40mm*4mm angle steel, or 30mm*30mm*3mm rectangular steel. The 2m~3.5m height letters' steel structure is slightly denser, and the 40*40*4 galvanized angle steel is also fully capable. If the luminous letter sign is larger than 3.5m, depending on the height of the equipment and the manufacturing process, the luminous component and the wind pressure are clearly defined, and then it is considered to be angle steel or square tube. Generally, the torsion resistance of the steel is stronger, and the structure of the large characters can be considered.
Smart Sign reminds users that companies that undertake the production of roof-lit advertising projects generally have a 2-3 year warranty. After the warranty period expires, the production company will no longer bear any responsibility, including security. This means a security risk. Therefore, after the end of the warranty period, even if the roof advertisement is not damaged, please go for a professional company to check and evaluate the safety.
