Yellow Wood 3 is an approximately 40,000-square-meter warehouse and office building in Samut Prakan, Thailand.

Groutec S couplers were used to connect precast concrete columns for easy and fast installation on the site. Groutec S has a smaller outside diameter which makes it slimmer and ideal for slim panels and narrow columns, thus making it useful in smaller scenarios.

Bartec couplers were also installed inside the precast columns as rebar splices.
