Why select 4S4

Variety

4S4 offers a complete line of products, ranging from roll-up doors to self supporting hallway partition systems and custom fabricated items

Experienced Personnel

4S4 includes a team of only the finest industry professionals, with vast experience in both the international and local self storage industries

Adaptability

Since our product is a non-structural and self supporting system, it is very adaptable to any configured unit mix

Superior workmanship

4S4 is the only supplier currently offering Third Generation doors in Africa. Dead axle design, harder steel, a tension adjuster, radial ball bearings and superior paint processes are all standard features of the 4S4 product line

Professional packaging

4S4 avoids drum wheel dents and other damage by not stacking our mini doors during shipping. All doors are individually suspended in crates, which relieves pressure and helps ensure your doors arrive in installation-ready form

Safety

Our doors are equipped with hemmed edges on components and tubular bracing on swing doors for maximum safety

Ease of installation

Our mini doors are shipped with the latch having been factory installed and the brackets pre-assembled to save time and money. In fact, our self storage doors can be installed in less than three minutes

Products that last

Doors must withstand a great deal of wear and tear, and replacing them is costly and time-consuming. 4S4’s doors are constructed of grade 80 steel, which effectively combats the dents and damage you'll find with other manufacturers
