Common questions about round modular balustrades

What post diameters are available for the round modular system?

SWR round modular posts are available in 42.9mm and 48.3mm. The right system depends on load requirements, building regs, fixing substrate and other bespoke elements. Speak to the team.

The round modular system supports toughened glass from 8mm up to 12mm in thickness. Glass is supplied and cut to your specified panel sizes. Laminated glass is available for overhead glazing or fall-arrest applications where required.

Yes. The round modular system is flexible by design — it can accommodate corners, changes in direction and stepped or ramped applications. Corner posts, step brackets and adjustable components are available to suit your specific layout. Confirm your geometry at quote stage and we’ll specify the correct components.

Under UK building regulations, a graspable handrail is required in most applications. The round modular system is available with or without a top handrail — if you’re specifying for a staircase or ramp, a handrail will be required. SWR supplies matching round or slotted stainless top rails to suit the system.

AISI304 grade is standard for most indoor and sheltered outdoor applications. AISI316 marine-grade stainless is available for outdoor, coastal, pool and high-humidity environments. Specify your environment at quote stage and we’ll confirm the correct grade.
