Trespa Shelving

Phenolic Resin Shelving units are strong, chemical resistant, solid homogeneous core with a hard rugged surface offering exceptional impact resistance, structural strength over long spans and dimensional stability.

Architects and Consultants have determined that Solid Phenolic Laboratory Shelving should be used in lieu of thin laminate over particle board or heavier epoxy resin or expensive stainless steel shelves. As a current trend, most architectural specifications indicate:
"A. Laboratory Shelving: Provide solid phenolic laboratory shelving where indicated on drawings in 3/4" (20 mm) or 1" (25 mm) as industry standard".

Laboratory shelving is typically specified in sections 11600 & 12345 of most equipment or laboratory furniture specifications.

Trespa® Solid Phenolic shelving is a thermo fused composite panel that is formed in presses under high heat and pressure to form a solid black core chemical resistant panel through its entire thickness. NO delamination is possible, edge banding is not required and the panels are light in weight with exceptional strength, which translates to value and cost effectiveness.


When tested to SEFA 8-1998 and NEMA LD3-2000 test methodology for 24 hours, solid phenolic resin shelving exhibits no effect when tested with common laboratory grade chemicals such as 33% sulfuric acid; 90% acetic acid; 37% hydrofluoric acid; 30% nitric acid; 85% phosphoric acid and many other chemicals as listed on our web site.

Trespa phenolic resin shelves feature excellent chemical and stain resistance. Solid composite panels require no edge banding, are not laminated, have no wood core and have excellent screw-holding capability for mechanical attachment to partition hardware or bench frames. Shelves can be easily cleaned and disinfected with a mild detergent solution.

TRESPA® TOPLAB®PLUS material is an ideal choice for durability and attractiveness. Highly resistant to chemicals and staining. Edges require no special treatment and can be easily profiled, milled, and polished to a 1/8" Bevel or 3/16" radius top and bottom. Colors available from stock: Black, Slate Gray, Silver Gray, Mystic White and Regular White.

Standard industry colors are Black Surface two sides, Black Core 1" (25.4 mm) thickness or alternatively 3/4" (20 mm), Black Surface / Black Core along with Slate Gray, Mystic White or Silver Gray solid phenolic surfaces. Trespa Shelving are stocked and available for immediate shipment or within a reasonable time after fabrication. Other surface colors or thickness' are available as a special production.

Edge treatments are standard industry specified as 1/8" (3.175 mm) bevel top and bottom; 1/8" (3.175 mm) radius top and bottom or full rollover edge with eased or radius corners. Surface texture for solid phenolic lab grade shelving is known as a crystal smooth finish with chemical resistant characteristics.

Anywhere where shelving units are required

Shelving units are typically 10" (254 mm) to 14" (356 mm) in depth and made up to 10'-0" feet (3.03 meters) in length or any size required within the standard panel length or depth. Intermittent supports are required based on actual use and physical weights applied to the shelving. See below for an example of shelving deflection guidelines.

The following table is only intended as a general guideline when considering the use of Trespa solid phenolic for shelving applications. The table is to be used to estimate the approximate weight that will cause a 1/4" (6mm) deflection when evenly distributed over a 12" (305 mm) deep span. The panel was supported on each end. The final determination regarding the stability of any material is the responsibility of the end user or specifiers, to ensure through independent testing, that the product selected meets all engineering and physical requirements of the intended application.|

*Loads can be affected by temperature, humidity, time, & other environmental factors.
End users should test shelves in appropriate environment and conditions.
It is assumed that deflection greater than 1/4" is undesirable aesthetically even though rupture has not occurred.
