Verified Feedback
Rated 4.9/5 on Google Reviews.
"The 0.5mm charcoal matte IBR sheets are absolutely stellar. They cut them to exact lengths, and the flatbed crane truck offloaded them cleanly onto our site within 4 days. Unmatched service."
"We replaced our old roof with Constant's Double Roman Terracotta concrete tiles. The quality is exceptional, and the tiles have completely transformed the modern look of our home!"
"We ordered structural pine timber and custom engineered trusses for a 12-unit residential cluster. Everything arrived fully SABS-certified and marked. All building inspectors signed it off with zero delays!"
"The CAD truss layout phase was incredibly accurate. Constant's engineering team mapped our roof pitch perfectly, and the SABS-compliance layout passed our municipal review on the first go."
"Outstanding craftsmanship. The seamless aluminum gutters match architectural standards perfectly, and their liquid waterproofing membrane is top-tier for preventing flashing leaks."
"Incredible direct procurement. We ordered 1,500 meters of corrugated sheets and structural timber for a warehouse development. Flawless site logistics and excellent commercial bulk pricing."
