Pultrusion Process
Pultrusion is a continuous process of raw materials, typically resin and reinforcing materials, forming profiles of constant cross section in continuous length. Pultrusion gets its name from the method by which the profiles are made. Raw materials are literally pulled by what we call "the puller." "The puller" is the machine made up of pulling pads, which grip the product, and a drive system which keeps the product moving. "The puller" is located just before the final cut-off saw. The process starts with the reinforcements. Typically, unidirectional glass roving is the fiber that runs along the length of the profile. Second, the fiberglass mat is added in, which is multidirectional reinforcement. Third is the resin, typically polyester or vinylester. The glass is "wet-out" with the liquid resin and pulled into a heated die. Just before all the material enters the die, surface veil may be added which enhances the final product's surface. Now that all the reinforcements have been "wet-out" and pulled into a heated die, the curing takes place. All the resins used in the pultrusion process have a catalyst or hardener added when the resin is mixed. This catalyst activated at about 200°F. Consequently, as the "wet-out" reinforcement pass through the heated die, the product changes from liquid to a solid profile with all the reinforcement laminated within. The product exiting the die is pulled by "the puller", which upon exiting can be cut to the desired length.
Standard Resin Systems for Structural Shapes STANDARD POLYESTER (ISO or PN) RESIN SYSTEM The STANDARD POLYESTER RESIN SYSTEM refers to a NON FLAME RETARDANT isophthalic polyester resin system. This resin system is manufactured in olive green and incorporates ultraviolet inhibitors. Polyester resins exhibit good corrosion resistance, good electrical properties, low thermal conductivity and excellent mechanical properties. FLAME RETARDANT POLYESTER (ISOFR or PF) RESIN SYSTEM This resin system exhibits the same characteristics as the Standard Polyester resin system PLUS a flame spread rating of 25 or less when tested in accordance with ASTM E-84. The FLAME RETARDANT resin system is manufactured in gray and yellow. FLAME RETARDANT VINYL ESTER (VEFR or VF) RESIN SYSTEM This resin system is manufactured from vinyl ester resin which exhibits higher strength, improved strength and stiffness retention at elevated temperatures, and improved corrosion resistance. This system also meets a maximum flame spread rating of 25 and is produced in beige and yellow. ELEVATED TEMPERATURE EFFECTS The approximate retention of mechanical properties at elevated temperatures are:

Chemical Resistance Guide - Structural Shapes The data in this chemical resistance guide is based on field service performance, laboratory testing and extrapolated values from our resin manufacturers' recommendation. Data shown is intended as a guide only. It is recommended that for a specific application, testing be done in the actual chemical environment. The following conditions will effect the suitability of a specific resin laminate: • Periodic changes in temperature • Exposure to frequent splashes and spills • Temperature spikes • Exposure to intermittent splashes and spills • Changes in chemical concentrations • Frequency of maintenance wash down • Combinations of chemicals • Load bearing or non-load bearing requirements • Exposure to vapors only

Columns - Allowable Axial Load Tables
8’ long - 6” x 6” x 1/2” Angle Full section column testing was conducted on equal leg angles, I and Wide Flange Shapes and Square Tubes. Ultimate values were generated through testing of elements with square cut ends placed between the table and the upper, moving platen of a universal testing machine. This test procedure closely simulates how FRP columns will generally be used in practice. Comparison of test data versus theoretical Euler buckling capacity suggests that the "K" value as tested is approximately 0.70, representing a fixed-pinned condition. The values in the tables represent an FS = 3.0 for the tested condition. Should you feel, however, that your column end conditions closely approximate a pinned-pinned condition ("rounded" column ends are somewhat difficult to achieve in practice) we recommend you multiply the allowable values shown in the tables by the following values:
SHAPE I, W or Angle Square Tube
To Obtain FS = 2.0 multiply by: 0.75 0.50 58
To Obtain FS = 3.0 multiply by: 0.50 0.33
