Frequently Asked Questions

Welcome to the Haysite FAQ page.  Should you have further questions, or need clarification, please free to contact us at any time.

DOES HAYSITE HAVE MATERIALS THAT MEET MILITARY AND IEC SPECIFICATIONS IN ADDITION TO NEMA SPECIFICATIONS?

Yes.  In addition, many Haysite materials are listed through Underwriters' Laboratories.  Review HTTP://IQ.UL.COM/SYSTEMS/to search and view Haysite's listed material designations.

HOW DO I CHOOSE BETWEEN THE PRODUCTION PROCESSES AT HAYSITE?

Haysite offers compression molding (SMC and BMC), and pultrusion (sheet and profiles).  Compression molding is a great fit for applications where the product complexity extends to three dimensions...  and where the glass and resin are expected to flow together. 

Pultrusion involves pulling the glass reinforcement, materials and resin through a die which serves the same purpose as a mold in compression molding.  The finished product is maintains very high properties in the direction of draw through the die...  As a result, corrosion resistance and structural applications are optimum for pultrusion. 

HOW MUCH DOES FLAT SHEET WEIGH?

Flat sheet weights can vary by material designation code.  Haysite offers a "light weight" version of sheet -DURACORE 1000.  Note the TRANSIT SECTION for further details.

WHAT ARE COMMON SHEET SIZES?

Haysite molded and pultruded sheet are available in 3' and 4' widths, with length usually at 8'.  Pultruded sheets are available in longer lengths, up to 12'.

WHAT ARE YOUR MACHINING SPECIFICATIONS AND TOLERANCES?

Haysite specs and tolerances are available in the following documents:

H950-PROPERTIES-TOLERANCES
LAMINATED SHEET WEIGHTS AND TOLERANCES

WHAT ARE YOUR STANDARD SHEET THICKNESSES?

Sheet thicknesses typically range from .031 to 2 inches.  Haysite is capable of producing most thicknesses upon customer request.

WHAT IS THE TOLERANCE FOR LENGTH AND WIDTH OF MOLDED PRODUCT?
AND LENGTH OF PULTRUDED PRODUCT?

NEMA grade tolerances are "typical" for Haysite molded and pultruded products.

WHAT LENGTHS OF ROD, ANGLE AND CHANNEL ARE AVAILABLE?

Haysite has several standard lengths for pultruded product.  Haysite will also provide product at custom lengths to meet customer designated length requests, increasing yield and minimizing "drop loss" in customer processes.
