Custom Fabrications


Questions we hear most often about custom fabrication

What material is best for the custom fabrication of a lab console or workstation?

Polypropylene is preferable for most uses. This resilient, high-strength material is the lightest in weight of any thermoplastic. It resists strong acids, alkalis and oxidizers and has excellent thermal insulating properties. It can be welded and thermoformed, has a high strength-to-weight ratio and resists cracking. Custom fabrications that use polypro are also economical, compared to other engineered plastics.

What materials are incompatible with polypropylene?

Polypro works well with a broad spectrum of chemicals and work conditions. Exceptions include applications involving aromatics, aliphatic solvents and chlorinated solvents

Can a polypropylene fabrication be used outdoors?

UV-stabilized polypropylene can be used outdoors.

How does polypropylene compare to polyethylene?

A polypropylene fabrication has lower impact strength, but superior working temperature range and higher tensile strength.

Is polypropylene suitable for a clinical environment?

Polypropylene is ideal for clinical and lab settings because it is mostly chemically non-reactive, resistant to high temperatures, and tolerant of sterilization.

Is polypropylene suitable for FDA/USDA applications?

Custom fabrications for food, pharma and other sanitary applications can be plastic, or stainless steel. The deciding factors are usually weight – polypropylene is substantially lighter – and cost. A polypropylene fabrication is lower in cost.

Stainless steel custom fabrications are often recommended for food processing applications. Is a polypropylene fabrication a better option?

The Tri-Mer downdraft table is suitable for all of these; if corrosives are present, polypropylene, rather than mild steel construction, is preferred.

We’re considering several custom fabrications for our manufacturing plant. Will a polypropylene fabrication withstand an occasional encounter with a forklift or hoist?

A polypropylene fabrication is resilient, with a high tensile strength. Polypropylene can be easily repaired if damaged by a forklift, or other device.
