What does it take to get a rooftop entry system ready for delivery? For our latest Hill Grwp TopBox project, the answer is precision engineering, careful planning, and teamwork at every stage.

This custom-built TopBox roof entry enclosure has just left our facility and is heading to site, where it will provide a safe, reliable, and cost-effective solution for controlled roof entry.


At Hill Grwp, we design and manufacture TopBox GRP enclosures to make roof entry safer, simpler, and longer-lasting — without compromising on quality.


TopBox is widely used across the commercial, industrial, water, and energy sectors, delivering robust and weatherproof rooftop entry solutions tailored to site requirements.
