What TuinMaximaal does
Tuinmaximaal is a Netherlands-based, privately held e-commerce and showroom retailer of aluminium terrace coverings, glass sliding walls, and related outdoor-living accessories, marketed under the Gumax® brand. The company designs and sources three core covering lines: Poly Line (entry-level, polycarbonate roof, from €799), Glass Line (most popular, glass roof, from €1,151), and Heavy Duty (6061-T6 aluminium, snow-zone rated, from €1,534), all modular and expandable with glass sliding walls, aluminium or polycarbonate side walls, shading panels, automatic sun awnings, LED lighting, screen doors, and electric patio heaters. All aluminium components are finished with the proprietary Gumax Excellence Superior Coating applied by AkzoNobel-Interpon, and aluminium support structures are produced under TÜV supervision to NEN 1090-1 with CE marking.
The company sells primarily through a self-serve model combining country-specific e-commerce websites (NL, BE, DE, FR, UK) with online configurators and 11 physical showrooms across the Netherlands and Germany, with professional assembly offered via external installation partners for non-DIY customers. Operations are supported by a 27,000 m² warehouse that holds the full product range in stock for rapid delivery, and the company employs over 250 people. Revenue derives almost entirely from one-time unit sales of hardware covering and accessory kits, with a 10-year warranty and a published lowest-price guarantee underpinning the value proposition. Brand awareness is amplified through recurring appearances on Dutch SBS6 television programs, including 'De Grote Tuinverbouwing' and 'Nederland in Beeld'.
