1)The explaination of pultrusion technique:
During the pultrusion process,the raw material are pulled through a heated steel forming die using a continuous pulling device. when the reinforcements are saturated with the resin mixture in the resin bath and the wetted reinforcement package is wrapped in a surfacing veil. the completed package then goes into a performer that roughly forms the package into the appropriate shape to enter the heated die for curing. the die is the exact shape of the final part desired. upon exiting the die, the part is over 90% cured and solid. the length of the part required is pulled through the cutoff saw and the process is complete.
 


 
2)Main Raw Material:
1.reinforcement material:fiberglass, glass mat, continuous strand mat, surfacing mat, needled mat.
2.basis material:unsaturated polyester resin, epoxy resin, vinylester resin.

3)Advantages of FRP pultruded grating:
. High Strength
. Exceptionally High Strength to Weight Ratio
. Lighter Weight 
. Accomodates Higher Loads at Greater Spans

1.4 PRODUCT DELIVERY AND STORAGE
 
A.       Delivery of Materials: Manufactured materials shall be delivered in original, unbroken pallets, packages, containers, or bundles bearing the label of the manufacturer.  Adhesives, resins and their catalysts and hardeners shall be crated or boxed separately and noted as such to facilitate their movement to a dry indoor storage facility.
 
B.       Storage of Products: All materials shall be carefully handled to prevent them from abrasion, cracking, chipping, twisting, and other types of damage.  Store adhesives, resins and their catalysts and hardeners in dry indoor storage facilities between 70 and 85 degrees Fahrenheit (21 to 29 degrees Celsius) until they are required.

PART 2 - MATERIALS
 
2.1 MANUFACTURER:
 
       A.  Structural shapes shall be MACHS® as manufactured by     
 
              Nantong Machs Composite Material Co., Ltd. 
 
2.2 GENERAL:    
 
A.       All structural shapes are to be manufactured by the pultrusion process with a glass content minimum of 45%, maximum of 55% by weight.  The structural shapes shall be composed of fiberglass reinforcement and resin in qualities, quantities, properties, arrangements and dimensions as necessary to meet the design requirements and dimensions as specified in the Contract Documents.
 
B.       Fiberglass reinforcement shall be a combination of continuous roving, continuous strand mat, and surfacing veil in sufficient quantities as needed by the application and/or physical properties required.
 
C.       Resins shall be {MACHS® ISO, non-fire retardant isophthalic polyester or ISO, non-fire retardant isophthalic polyester used to produce Standard 61 certified shapes; ISOFR, fire retardant isophthalic polyester; VE, non-fire retardant vinyl ester used to produce Standard 61 certified shapes or VEFR, fire retardant vinyl ester, (choose one)} with chemical formulation necessary to provide the corrosion resistance, strength and other physical properties as required.
 
D.       All finished surfaces of FRP items and fabrications shall be smooth, resinrich, free of voids and without dry spots, cracks, crazes or unreinforced areas.  All glass fibers shall be well covered with resin to protect against their exposure due to wear or weathering.
 
E.        All pultruded structural shapes shall be further protected from ultraviolet (UV) attack with 1) integral UV inhibitors in the resin and 2) a synthetic surfacing veil to produce a resin rich surface.
