Why W SUN

One contract, start to finish.

One team handles your project from the first plan to ongoing maintenance — and one call if anything goes wrong.

01Delivered audit-ready — what an NSF audit checks is designed and built in from the start.

02We build around your production — phased, off-peak work, so the line never stops.

03Built to expand — utility capacity planned ahead for your next line.

“W SUN completed our facility renovation on time and up to standard, and production was never affected. A partner you can trust.”
— Ocean Formulations Inc.

Built for GMP. Ready for audit.

GMP is the legal standard for making food, dietary supplements, cosmetics, and drugs. We build what auditors look for into the design and construction — so the facility is ready for its NSF audit the day it's delivered.

Cleanrooms:ISO-class rooms with easy-clean walls, seamless epoxy floors, and HEPA filtration
Pressure & HVAC:clean zones positive, dirty zones negative; temperature and humidity held constant
Zoning & flow:receiving, storage, production, packaging, and inspection kept apart; people and materials flow separately
Floors & access:heavy-duty epoxy in high-load areas; high-speed doors cut cross-contamination
Audit details:pest control, drainage, dust-free fixtures — handled during construction, not after

Build it right the first time — it costs far less than retrofitting later.
