Grand Slam sports equipment is engineered for strength and reliability. Our outdoor equipment is designed for even the most extreme conditions, and can be supplied for wind areas rating from W33 to W50. Our indoor equipment is also designed and built to meet the most rigourous safety and quality standards. Wherever possible we manufacture our products from long-lasting, highly durable galvanised steel, which is (where stated) powder-coated in high grade polyester to give years of maintenance-free use. Products that are manufactured from standard grade steel for outdoor use are, wherever possible, hot-dipped galvanised after fabrication. These products can also be powder-coated or painted if desired to suit your needs.
