IMPORTANT NOTES


1. SELECTION CRITERIA 1. Select appropriate grating material depending on service conditions 2. Determine applicable load conditions and impact factors 3. Determine the span of grating support structure 4. Select appropriate GRATEX® from the Load/Span Tables

2. LOADINGS 1. U, kg/m2, maximum allowable unfactored uniformly distributed loading for that stated span 2. C, kg/m, maximum allowable unfactored centre line load per metre 3. Load/Span Tables based on elastic deflections of span/200 or 10mm, whichever the lesser when subjected to the specified unfactored load using Young’s modulus, 200x109 Pa 4. For serrated grating reduce tabulated allowable loads by 10% and maximum span per load category by 3.5% 5. All table loadings to be taken as nominal and should not be used as guaranteed values 6. Appropriate safety factors must be applied by the designer

3. ALLOWANCES 1. Galvanising will increase stated mass per square metre by approximately 8 – 10% 2. Banding will increase mass by approximately 6% depending on grating configuration

GW40® CARBON STEEL GRATINGAround the world … whether the United States, Europe, or the Far East … the definitiveinternational grating standard. Jig assembly and automatic resistance welding (forgewelding) creates structurally rigid grating, with load bearing bars and transverse bars fused under pressure. There’s no need for the manual assembly, punching, threading and swaging previously used for South African grating.GRATING WORLD now brings you FORGEWELD® GW40® resistance heated and fused CARBON STEEL GRATING with special 6mm and 8mm twisted transverse bars for improved skid resistance. Serrated edge load bearing bars may be specified for especially slippery conditions.Without a doubt, FORGEWELD® GW40® CARBON STEEL GRATING offers the most economical solution for most environments.Still not sure? Ask us for a head-on physical demonstration of the two grating types.

FORGEWELD® GW40® UNSERRATED CARBON STEEL GRATINGLOAD/SPAN TABLES

Suggested RangeNB: Deeper bearer bars available

GW40® CARBON STEEL GRATING


GRATELOK® GL40® CARBON STEEL GRATING is constructed by inserting round transverse bars through punched rectangular bearer bars, then swaging (pressure deforming) the transverse bars on each side of bearer bars. This produces a neat and rigid assembly with structural integrity. The range is designed in accordance with DIN, BS and NAAMM standards.

GRATELOK® GL40® CARBON STEEL GRATING is available with serrated load bearing bars for improved skid resistance in especially slippery conditions, or with non-serrated bearer bars for normal conditions. Bearer bars are 3mm and 4.5mm thick, with depths of 25mm, 30mm, 40mm, and 50mm. Heavy duty bearer bars of 6.0mm wide by 75mm or 100mm deep are available on request.

The standard bearer bar pitch of 43mm provides effective spacing of 38.5mm (British Standard) or 45.5mm. Extended spacing of bearer bars and transverse bars are available on request, viz. GL40® 43/50, GL40® 43/100, GL40® 86/50 and GL40® 86/100.

Standard panels are 2400mm by 1200mm. Special sizes and customizing are available on request.

Finishes include mill (standard), coated (painted or powder coated), bitumenised, and galvanized.

GRATELOK® GL40® CARBON STEEL GRATING offers an economic grating solution for most environments.

The Load/Span tables are based on a maximum tensile stress of 165 MPa and elastic deflections of not more than span/200 or 10mm, whichever is the lesser when subjected to the appropriate unfactored load4. All the above to be taken as nominal and should not be used as guaranteed values

MOULDED PULTRUDED

GRATEX® FRP FIBREGLASS GRATING - MOULDED& PULTRUDED is a cost effective, lightweight solution for walkways, platforms, gullies, trenchesand mezzanines.

GRATEX® FRP FIBREGLASS GRATING - MOULDED& PULTRUDED has a high strength to weightratio, is corrosion resistant, and is slip resistant.It exhibits low thermal conductivity, is non-magnetic and non-sparking.

Both grating types provide excellent impact and loading characteristics.

GRATEX® FRP FIBREGLASS GRATING - MOULDED& PULTRUDED is available in three resin types:

n Isophthalic Polyester - moderate exposure to corrosive elements; and a low flame spread rating of 25 or less

n Vinyl Ester - for resistance to both acid and alkaline environments; and a flame spread of 25 or less n Phenolic - provides the ultimate fire resistance; designed to withstand prolonged fire exposure without sustaining structural damage.

GRATEX® FRP FIBREGLASS GRATING - MOULDED& PULTRUDED is easy to install, requiring only acircular saw, jig saw or angle grinder.

Standard moulded panels are 1220mm x 2440mm and 1220mm x 3660mm. Special sizes andcustomising are available on request.

HANDRAILING - FRP (COMPOSITE)The GRATING WORLD RAILEX® FRP Handrail System is of 50mm diameter round and 50mm square tube design, using internal fittings for all connections. Joints are bonded and mechanically fastened using either metallic or non-metallic hardware.

RAILEX® FRP Handrails are fabricated from Safety Yellow fiberglass pultrusions using a fire retardant resin with 50% glass content and a surface veil for protection against ultraviolet damage. RAILEX® FRP Handrails have a Class I fire retardance, with an ASTM E-84 flame spread rating of 25 or less.

FRP (Composite) Advantages:

• High Strength • Lightweight • Increased Life • Easily Assembled • Low Maintenance • Dimensionally Stable• Chemical Resistant • Corrosion Resistant • R.F. Transparent • Fire Resistant • Non-Conductive (Electrical)• Non-Conductive (Non-Magnetic)

COMPONENTS AND COMPLETE ACCESS SYSTEMS

GRATING WORLD supplies FRP components and fabricates walkways, stairways, platforms, handrail systems, caged ladders, fixed ladders, and support systems that are specially designed and engineered for corrosive environments according to your specified workloads and configurations. Units are shop assembled and shipped in sections to minimise field installation.

GRATING WORLD RAILEX® standard FRP handrailing components are manufactured from general purpose isophthalic polyester resin, with good corrosion resistance.

Available on request are components of fire retardant isophthalic polyester resin with a Class 1 fire retardance, with an ASTM E-84 flame spread rating of 25 or less and low smoke generation. Also available are components of fire retardant vinylester resin. It is highly corrosion resistant and capable of higher surface temperatures.
