Spill containment trucks and dollies are typically constructed from materials that are durable, chemical-resistant, and capable of withstanding harsh environmental conditions. Common materials include:
1. **Polyethylene (PE):** High-density polyethylene (HDPE) is frequently used due to its excellent chemical resistance, durability, and lightweight nature. It is non-reactive with most chemicals, making it ideal for containing hazardous spills.
2. **Steel:** Carbon steel or stainless steel is often used for its strength and durability. Stainless steel, in particular, offers corrosion resistance, which is crucial for handling corrosive substances.
3. **Aluminum:** Lightweight and resistant to corrosion, aluminum is sometimes used for spill containment equipment, especially when weight is a concern.
4. **Fiberglass:** Reinforced fiberglass is used for its strength, chemical resistance, and ability to withstand extreme temperatures. It is often used in environments where both chemical and thermal resistance are required.
5. **Rubber and Elastomers:** These materials are used for gaskets, seals, and wheels on dollies to provide flexibility, chemical resistance, and shock absorption.
6. **Composite Materials:** These are engineered materials made from two or more constituent materials with different physical or chemical properties. They are used to enhance the strength, durability, and chemical resistance of spill containment equipment.
These materials are selected based on the specific requirements of the spill containment application, including the types of chemicals being handled, the environmental conditions, and the need for mobility and ease of use.
