Corrosion ResistantUnlike conventional metals, Leadergrate products eliminate the rusting and corrosion problems associ-ated with traditional materials. The corrosion resistance is achieved by the choice of the resin and is enhanced by adding chemical resistant veil to the external surface of the pultruded pro�les. Additionally, special UV inhibitors included in the formulation provide extra protection from the e�ects of weathering.
Light WeightAt only 12 kgs/m2 for 25 mm thick grating and 18kgs/m2 for 38mm thick grating, leadergrate grating is very easy to install, to remove and lift without the help of heavy lifting equipment. Fiberglass grating weighs 1/3 the weight of steel grating, resulting in lower installations cost.
UV Resistant & Durability Our products are suitable for 100% humidity and temp > 100 oC and UV resistant by adding UV inhibitor in the resin and a synthetic veil to the external layer of pultruded products, hence creating a resin rich surface.
High Sti�ness Our Grating are manufactured using a proprietary method enabling a high percentage of glass rovings to be introduced into the grating. Possessing a higher glass content results in a sti�er �berglass grating. The glass content for molded grating can vary between 25-38% and can be increased to 43% in special cases. The Pultruded grating possesses approximately 65 % of Glass content by weight giving it the very high strength to weight ratio. Load bearing bar capacity can be tailored to the application by modifying the glass content, �ber orientation and combination of mat and roving reinforcement. The grating platform can be designed with live load starting from 250 kgs/m2, 500 kgs/m2 , 1000 kgs/m2, 1500 kgs/m2 up to a maximum load 40 tons/m2.
GENERALINFORMATION
02
Leadergrate molded and pultruded grating are developed for corrosive applications where light weight, impact resistant, corrosion resistant and slip resistant grating is a must. The molded grating is a combination of glass rovings strategically positioned within thermoset resins to form a one-piece, high resin content product. The pultruded grating is an assembled grating from pultruded bearing bars, manufactured by the “ PULTRUSION PROCESS “ to form a high glass content product.
Quality Manufactured Product Leadergrate is an ISO 9001 certi�ed company. The gratings are manufactured complying to ASTM & BS standards. Every panel of grating is subjected to a number of quality assurance inspections ensuring void free panels, full wet-out of the glass rovings, consistent non skid features. Complete traceability of resin batches and the glass utilized in every panel is maintained and can be provided as needed. Chemical resistant tests, and load capacity are routinely performed.
Pultruded Grating Pultrusion is a continuous molding process using �ber reinforcements with thermosetting resin matrices. Pre-selected reinforcement materials, such as �berglass roving, mat, woven fabrics are drawn through a resin bath in which all material is thoroughly impregnated with a liquid thermosetting resin. Typical resins include polyester, vinylester and phenolics. The wet out �ber is formed to the desired geometric shape and pulled into a heated steel die. Once inside the die, the resin cure is initiated by controlling elevated temperatures. The laminate solidi�es in the exact cavity shape of the die and is continuously pulled by the pultrusion machine.
Molded GratingManufacturing process is open heated molding. Continuous glass �bers are placed in the mold in alternating layers and completely wetted out with resin. This continuous process produces an integral, one piece construction which provides excellent corrosion resistance as well as bi-directional strength. When the weaving process is completed, the mold is heated to cure the panel. The mold will receive the grit before the part is cured. After curing the part is extracted from the mold. Many types of mesh sizes and panel sizes can be obtained as per di�erent molds design.
Moltruded GratingMoltruded grating has been designed to combine the one piece construction of molded grating with the unidirectional sti�ness of pultruded grating.

STAIR TREADS
Leadergrate �berglass stair treads are o�ered in two varieties :
The Molded Tread &The PutltrudedTread
Our stair treads are cut from the Panels measuring 565x3050 mm. The mesh of the Molded Tread is 25x150 mm with double bearing bars at the 150 mm intervals so that any stair tread with a length that is a multiple of 150 mm is always banded. Our Stair Treads meet OSHA safety code standards, are closed on all sides, with gritted surface and a solid black color nosing.
Alternatively, Molded Tread is manufactured from regular 38 thick, 38x38 Square mesh grating with a fabricated structural nosing.

DESCRIPTION APPLICATION
GRP SUPPORTSYSTEM
35
Leadergrate o�ers a wide range of structural components for supporting the Grating or covers platforms .
• GRP Reverse angle anchored in the concrete wall.• GRP Y angle embedded in the concrete.• GRP Seating L shape angle �xed in concrete notch.• Thermoplastic adjustable legs.• GRP Stationary pedestal.• GRP Pultruded Beams.• GRP Pultruded Columns.
Leadergrate use the pultrusion process to produce the structural pro�les taking in consideration the following factors :
E�ect of temperature: The result of higher temperature on structural �berglass is a reduction in modulus of elasticity and thus lowering of the allowable stresses. The retention of Modulus of Elasticity and ultimate stress are considered in the design. Vinyl ester resin are better in elevated temperatures than polyester resins.
E�ect of corrosion: The environment dictates the type of resin to be used, and the di�erent resins possess di�erent structural properties. In essence, the use of a polyester resin in designing a �berglass structure will have lower allowable stresses and higher de�ections than would the use of a vinyelster resin in the same environment.
De�ections: Unlike steel, due to �berglass Low shear modulus, the total de�ection of a �berglass beam is actually comprised of two components:
- Flexural De�ection - Shear De�ection
E�ect of weathering: Fiberglass will undergo some decay and change of appearance due to prolonged exposure to outdoor weathering. A condition called “Fiber blooming“ will occur on the surface. the use of UV stabilizers in the resin and surface veils, synthetic type enhances weather ability and corrosion resistance by adding resin thickness to the surface of the product. The optimum method of maintaining surface appearance during outdoor exposure is to apply a coating to the surface. Two-component, UV stabilized urethanes work very well with this application.
