DURA GRATING - TECHNICAL SPECIFICATIONS - October 2018

Transcription

1 DURA GRATING - TECHNICAL SPECIFICATIONS - October Definition Glass-reinforced plastic (GRP or fibreglass) is a composite material made of a thermosetting plastic resin reinforced by fine fibres of glass along with the use of additives and is commonly referred to by the name of fibreglass 1.1 Applications GRP is an immensely versatile material which combines lightweight with inherent strength to provide a resilient finished product with a variety of surface textures and a virtually unlimited colour range available. By selecting the appropriate combination of fibreglass reinforcements, resins and processing techniques, the engineer can create a product or component to meet the most demanding of specifications. 2.1 Benefits High strength, light weight, dimensional stability, corrosion/chemical/electrical resistance, low tooling/installation cost, long life. GRP products compete very favourably on a performance/life cycle cost basis versus traditional materials. 2.2 Open Area Dura Grating Standard 25mm, 30mm, 38mm thickness panels have a 68% Open Area. Dura Grating Standard 13mm, 50mm thickness panels have a 78% Open Area. Dura Grating Mini 14mm, 22mm, 30mm, 38mm thickness panels have an Open Area of 42% Dura Grating Micro 22mm, 30mm thickness panels have an Open Area of 36% 2.3 Raw Material Characteristics Two main components produce composite GRP: polyester resin and glass fibres. Isopthalic polyester resin is used to manufacture Dura Grating Standard Mesh due to its great compromise of performance and cost. Orthopthalic resin used to manufactuer Dura Grating Mini Mesh and Phenolic & Vinylester resin is available by special order according to project needs. 2.4 Typical Material Properties Resin Glassfibre Density kg/m³ (Specific Gravity) Hardness (Barcol) Tensile Strength Mpa Modulus of Elasticity GPa / (Tensile Modulus) Compressive Strength MPa Flexural Strength MPa Interlaminate Shear Strength MPa Na 9 Water Absorption % Voltage breakdown (k volts/mm) - 18 Thermal Conductivity W/m o C Max Operating Temp (deg. o C) Specific Heat (kj/kg o C 2.3 na 2.5 Product Dura Grating is a moulded non-slip composite floor grating system constructed from fibreglass as an ideal and cost effective alternative to traditional floor grating materials like mild steel, stainless steel grating, aluminium or wood. Dura Grating grid flooring is durable, lightweight and chemical and corrosion resistant which makes it ideal for the industrial, chemical, construction and shipping industries.
