Description

What are the advantages of FRP ladders compared to aluminum ladders?

Compared with aluminum alloy ladders, FRP ladders have the following advantages:

Insulation performance

FRP ladders: have excellent electrical insulation, withstand 250kv/M power frequency test voltage, can be used safely in live working or near electrical equipment, can effectively prevent electric shock accidents, and ensure the personal safety of users. They are especially suitable for workplaces with high insulation requirements such as electricity and electricity.

Aluminum alloy ladders: Aluminum alloy is a good conductor and has conductivity. There is a greater safety risk when it is close to the power supply or live working, which is easy to cause electric shock accidents. Therefore, it cannot be used in environments with risks of electric shock.

Corrosion resistance

FRP ladders: have strong resistance to oxidation by the atmosphere and water, as well as various solvents such as acids, alkalis, and salts of general concentrations. It is not easy to rust, rot, or be corroded by chemicals. In harsh environmental conditions, such as humid, acidic, and alkali corrosive environments, FRP The ladder has a longer service life and lower maintenance costs. It can be widely used in chemical, marine, food processing and other industries.

Aluminum alloy ladder: Although aluminum alloy has a certain corrosion resistance, long-term exposure to harsh environments, such as moisture, acid and alkali, may still cause corrosion, affecting the service life and safety of the ladder. Regular cleaning and maintenance are required to prevent corrosion.

Strength to weight ratio

FRP ladder: The relative density is between 1.5-2.0, which is only 1/4-1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel. The specific strength can be compared with high-grade alloy steel. While ensuring sufficient strength, it is lighter and easier to carry and use.

Aluminum alloy ladder: The aluminum alloy ladder itself is also light in weight, but the FRP ladder has more advantages in strength to weight ratio, that is, the FRP ladder has higher strength at the same weight, or when the same strength requirements are met, the FRP ladder is lighter.

Thermal conductivity

FRP ladder: The thermal conductivity is low, at room temperature 1.25-1.67kJ/(m・h・K), only 1/100-1/1000 of metal, is an excellent thermal insulation material. When in contact with high-temperature objects or in a high-temperature environment, it will not heat up as quickly as a metal ladder to cause burns to the user, and has good thermal protection performance.

Aluminum alloy ladder: Aluminum alloy has good thermal conductivity, and its thermal conductivity is much higher than that of FRP ladder. When used in a high-temperature environment, the surface temperature of the ladder will rise rapidly, which is easy to burn the user, and there are certain safety hazards.

Appearance and color

FRP ladder: novel appearance, various colors, generally yellow and other eye-catching colors, and the colorant does not contain heavy metal substances, harmless to the human body, in line with relevant standards, while meeting the use function, it can also play a certain decorative role, improve the overall aesthetics of the workplace or home environment, and has good durability, not easy to fade or deform.

Aluminum alloy ladder: The color is relatively single, generally silver or aluminum primary color. Although other colors can be obtained through surface treatment, the durability and aesthetics may not be as good as FRP ladders. Scratches and fading are prone to occur during long-term use, affecting the appearance.

Anti-slip performance

FRP ladder: The surface of some FRP ladders will be specially treated to increase anti-slip texture or use anti-slip materials to improve the safety of the ladder during use, prevent users from slipping and falling, and maintain a good anti-slip effect even in a humid or greasy environment.

Aluminum alloy ladder: It is usually necessary to add anti-skid patterns or install anti-skid pads on the pedals to improve the anti-skid performance, but the anti-skid effect may not be as good as FRP ladders, and parts such as anti-skid pads may wear or fall off after long-term use and need to be replaced in time.

Designability

FRP ladder: Ladders of various structures, shapes and sizes can be flexibly designed according to different usage needs and places to meet specific usage requirements, such as different heights, angles, pedal shapes, etc., and specific performance requirements of the ladder in terms of corrosion resistance, strength, insulation, etc. can also be achieved by selecting different materials and manufacturing processes.

Aluminum alloy ladder: Although it also has a certain degree of designability, due to the material characteristics of aluminum alloy and the limitations of processing technology, its design flexibility is relatively small, and it is difficult to achieve some complex shapes and structures.

Maintenance cost

FRP ladder: No special maintenance such as rust and corrosion prevention is required on a regular basis. Just wipe with a damp cloth or rinse with a mild detergent to keep it clean. It has a long service life and low maintenance cost for long-term use.

Aluminum alloy ladder: It needs to be cleaned regularly to prevent dust, oil and other substances from corroding the surface of the ladder. It is also necessary to check whether the connection parts are loose, and perform maintenance work such as tightening and lubrication when necessary. The maintenance cost is relatively high.
