Why moulded grating over steel grating?There are certain applications where steel gratings are not suitable. The environment is either corrosive or a high maintenance headache. Steel grating is very heavy in comparison and the load must be designed into the supporting structure. After installation it begins to rust in wet or corrosive environments. Maintenance Departments constantly submit maintenance improvements to their budgets, adding further cost. Also, most steel gratings have little or no anti-slip resistance. Slipping causes most accidents in the work place. How does moulded grating compare in price to steel grating?Steel grating normally sells for around £25 to £35 per square metre, aluminium grating around £65 to £75 per square metre, and stainless steel for around £95 per square metre. Moulded grating averages around £60 per square metre, but is the lowest when you consider ‘Life Cycle Costs’ along with the anti-slip benefit. Why the ‘square’ grid pattern?Rectangular steel grating and some rectangular moulded grating has good deflection only in one direction. With a square grid pattern, deflection is in both directions and cannot be installed incorrectly. Square grid patterns allows access holes to be cut from the centre of the panel, and does not degrade the strength of the panel in any way. For most projects, the ease of cutting lowers costs since it can be done without specialist cutting and welding equipment. It is also light enough to avoid the need for cranes. Cut outs can be made in the grating for pipe work etc. and because the bearing bars bear in both directions, extra support is not required. What colours are Fibreglass Grating available in?Green is the industry standard colour but light grey is also a stock colour. For larger quantities, fibreglass grating can be manufactured in any RAL colour. Fibreglass Grating Ltd have supplied many different colours to a wide range of clients. What are the standard panel sizes?For larger projects we can supply panels manufactured to the customers exact size. Standard panel sizes are 2m x 1m, 3m x 1m, 4m x 1m and 3.66m x 1.22m. We also offer all customers a free of charge cutting and resin sealing service. How does fibreglass gratings strength compare with steel?For pedestrian traffic and medium loadings, fibreglass grating is perfectly adequate. On some occasions it can be used in heavy load situations. For example in narrow drainage gullies. As a basic guide, our 25mm grating will comfortably withstand 1/3 ton per square metre and the 38mm 1/2 ton per square metre. These figures are based on 1 metre wide gratings supported on 4 sides. If the width is smaller and the correct support is provided, these figures can be multiplied many times. For example, at 300mm wide, our 38mm grating can withstand loadings in excess of 12 tons! How does the customer justify the extra cost over steel grating?Consider these important points: 1) Reduced support structure. 2) Ease of installation. 3) Zero Maintenance. 4) Easily lifted by one or two people. Overall, the life cycle costs of moulded fibreglass grating will be much less than steel. Top What is the difference between grit and concave surface?Both surfaces offer excellent anti-slip properties. There are circumstances where a grit surface can be a problem. For example, grit particles could get into delicate machinery or food products. The addition of a quartz grit surface prolongs the life of the grating and is recommended in heavy use areas. Are there other resin systems available?There are three types of resin systems available. Orthophalic is an industrial grade resin used in non-corrosive situations. Isophthalic is a superior grade of resin, which meets most corrosive applications. Vinyl Ester resin is the highest quality, and used only in extreme situations. In addition to improving safety standards Dura Tread Fibreglass Grating provides excellent chemical resistance is easy to install and offers long term durability. The gritted anti-slip surface has one of the highest degrees of slip resistance ever measured for a walking surface. Consideration should be given to installing Fibreglass Railing, Drainage Channel Grating, Fibreglass Drain Covers, Glassfibre Steps, GRP Flooring, GRP Drain Covers, Health and Safety Flooring, GRP Gully Covers, FRP Drain Covers and Glassfibre Grates. These products are ideally suited for Stair Tread, Steps, Anti Slip Stairs, Outdoor Stairs, Non Slip Stairs and Non Slip Stair Treads. |
