The frame of this Dining Set is made with Grade 304 stainless steel & contains a film of chromium oxide which prevents surface erosion making it ideal for outdoor use. The table top is constructed of High Pressure Laminate (HPL). This is produced by combining thermosetting resin with kraft paper under high temperatures. The result is an extremely tough & weather resistant material. It is not susceptible to weathering, mould or rot. Covering the chair frame is a tough synthetic fabric made from PVC coated polyester. It has specifically formulated yarns that withstand UV fading, mildew & severe weather conditions. The fabric is fully water resistant & can be cleaned using soapy water. This large dining table is perfect for outdoor dining. It seats up to 10 people, so is ideal for entertaining family & friends. It is virtually maintenance free… warm soapy water for cleaning is all that is required.
