When it comes to the selection of ladder material for industrial use, two popular ladder types are FRP ladders and aluminium ladders. The reason behind their popularity is due to their durability and lightness, but the two materials behave differently in the presence of chemicals, water, electrical and corrosion.
Therefore, which ladder type is better: FRP ladder or aluminium ladder for industrial use?
In an industrial setting, FRP ladders may have several benefits over aluminium ladders depending on the situation. But aluminium ladders could also be more appropriate in certain cases.
Plastic fabrication is the process of making industrial products from plastic materials like PP, PVC and FRP through operations like cutting, welding, forming, machining, molding and laminating.
Common uses of these products include chemical industries, pharmaceutical industries, electroplating industries, water treatment industries and manufacturing industries.
The choice of material to use will depend on aspects such as chemicals, temperature, loading, size and use.
This is one of the major strengths of FRP in an industrial setting. An industrial facility can potentially expose ladders to: Acid fumes Alkalis Salts Water Humidity Chemicals Other corrosives FRP is by nature resistant to corrosion and will not produce rust in the traditional sense. Aluminum does not rust like steel, but it can still corrode under certain chemical conditions.
Another benefit of FRP is that it is non-conductive when produced according to proper methods. As such, FRP ladders can be safely used near electrical equipment. Since aluminium is a metal, it is conductive. This means that aluminium ladders must observe safety procedures around live electrical systems. In terms of electrical insulation, FRP offers an obvious edge. Noteworthy: FRP must not be assumed to replace necessary electrical safety procedures. It is imperative that the ladder in use be considered.
Chemical exposure may take place due to spills, fumes or the ambient air on industrial ladders. FRP offers chemical resistance but the effectiveness of its performance varies from case to case depending upon the resin system used, chemical involved, concentration, temperature and duration of exposure. Aluminum may not be suitable in some chemical environments. This is why FRP becomes especially suitable for chemical processing, electroplating and waste water treatment systems.
Both have relatively low weights compared to steel. Aluminum seems to take the lead for weight and easy handling. FRP, on the other hand, is also relatively light but provides the added benefit of being resistant to corrosion and electrical conductivity. When it comes to fixed industrial ladders, weight becomes a less significant factor.
Properly designed, both FRP and aluminum offer sufficient strength. FRP has an excellent strength-to-weight ratio and can be manufactured for industrial purposes. Aluminum is also strong and portable, and hence its extensive use in such areas. However, when selecting a ladder for industrial projects, do not base your choice on name alone. Look into the following: Dimensions of ladder Size of sections Load capacity Design of rungs Support system Manufacturing quality Method of installation
There are no requirements for repainting and anti-corrosive coatings that are needed for some steel constructions. It can be especially beneficial when there are problems related to the maintenance of metals because of the moist and chemical environment. Inspection remains a necessary procedure for both types of materials. It is necessary to check the ladder for any damage and other signs of degradation before its usage.
An FRP ladder may suit your needs if you are looking for one for use in:
Environments involving the presence of corrosive chemicals: Such would be the case in chemical plants or processing areas.
Electric installations: The nonconductive characteristics of FRP may prove to be useful.
Very humid or wet conditions: FRP will not rust like normal metal ladders.
Industrial environments outdoors: FRP may do well in difficult weather conditions.
Low maintenance needs: Rust-resistance may make the ladder low maintenance over its lifetime.
| Feature | FRP Ladder | Aluminium Ladder |
|---|---|---|
| Corrosion resistance | Excellent | Good, but can be affected by certain environments |
| Chemical resistance | Excellent for many industrial applications | Limited depending on chemical exposure |
| Electrical conductivity | Non-conductive | Conductive |
| Weight | Lightweight | Very lightweight |
| Strength | High strength-to-weight ratio | High strength-to-weight ratio |
| Outdoor use | Excellent | Good, application dependent |
| Maintenance | Low | Low |
| Industrial chemical environments | Highly suitable | Application dependent |
| Electrical environments | Advantage due to non-conductivity | Requires caution |
| Custom fabrication | Available | Available, depending on manufacturer |
However, in the following situations, using aluminium might be a viable choice because:
Aluminium ladders are constructed using aluminium, which is a light metal that has high strength properties and is easy to manipulate.
Applications of Aluminium Ladders include:
The major strength of aluminium ladders lies in their light weight, allowing for ease of transportation and positioning.
But aluminium is a conductor of electricity and may not be suitable in different chemical and environmental conditions.
There is no winner that suits all.
FRP should be preferred if:
Corrosion resistance + chemical resistance + non-conductivity + easy maintenance are crucial factors.
Aluminium should be preferred if:
Weight reduction + portability + universal access are the key considerations.
For many industries, especially for chemical, waste water, electroplating and electrical installations, FRP may become a more appropriate choice due to its properties.
When selecting a FRP ladder, one should not consider height alone before placing an order for the product. Some considerations include:
Giving a sketch, site dimensions, or even pictures will assist the manufacture in recommending a suitable design.
Choosing FRP or Aluminium depends on the application of the ladder.
In case of general maintenance work where portability is the key, aluminium may seem like an ideal choice.
However, in the case of chemical industry, sewer plants, electric plants, coastal areas, etc. where corrosion is the major problem and safety of workers is important, FRP would give better results because of its enhanced combination of corrosion resistance, non-electricity conductance, durability and minimal maintenance.
The best ladder therefore is not always the lightest or cheapest ladder; it is the one which suits your requirements of environment and loading.
