How Long Can Keruing Glulam Span? The Question Every Architect Asked
From Warehouse to Pavilion
When Timberlab, a timber construction company, approached Buana with a vision for IFEX 2026, the parameters were clear: Tangkup Pavilion, a one-bedroom villa topology suspended from a single column, with cantilevered arms reaching outward in a geometry of balance and risk. To realize this vision, Buana supplied 5 cubic meters of keruing, transforming raw hardwood into precision-engineered components.
Three Weeks: Manufacturing Custom Dimensions
In just three weeks, Buana manufactured custom-size glue laminated timber to meet exacting architectural specifications. Five cubic meters of premium GLTAA certified glulam transformed into 11-meter beams, 5-meter columns, and 12-meter trusses along with the rafters, purlins, and supporting elements that would become the Tangkup Pavilion.
Each piece of keruing glulam was engineered not merely to size, but to performance. As a glulam manufacturer in Indonesia, Buana understands that custom dimensions mean nothing without corresponding structural integrity. Every beam, every column carries the density and natural durability of keruing.
Two Weeks: Fabrication and Finish
Production continued through fabrication and coating, two additional weeks where raw strength met refined aesthetics. The glulam components received a rustic dark brown finish, a coating chosen not to hide the wood but to enhance what was already there. The result added warmth and texture to the pavilion, transforming engineered timber into an architectural experience.
For visitors walking through Tangkup Pavilion, the finish did more than protect. It invited touch. It reminded everyone that GLTAA certified glulam can be simultaneously structural and sensory, capable of bearing loads while creating atmosphere.
Beyond Structure: The Proof in the Pavilion
Tangkup Pavilion proved something that Buana has known for years: keruing glulam can achieve more than just structure. It can create space. It can shape experience. It can warm an interior with the natural richness that only genuine hardwood provides. The 11-meter beams spanning above visitors' heads carried more than roof load. They carried the weight of the possibility that timber construction in Indonesia has entered a new chapter.
The Road Ahead for Buana Keruing Glulam
IFEX 2026 is complete. The pavilion has been experienced, photographed, discussed. But the implications extend far beyond a single exhibition.
As more architects and engineers discover what GL20-grade keruing glulam makes possible, the projects will grow more ambitious. Longer spans. More daring geometries. Heavier loads. Buana stands ready with certified material, proven manufacturing capability, and the experience gained from three weeks of intense collaboration that produced something remarkable.
