Import Balau / Bangkirai Decking & 3 Layers Door Jamb — Buy in Bulk from Supplier in Indonesia

CV Indo Bina Mandiri offers Balau (Shorea spp.) and Bangkirai (Shorea laevis) decking alongside three-layer door jambs manufactured from these dense tropical hardwoods. Balau and Bangkirai represent some of the most durable exterior timber species from Southeast Asian dipterocarp forests, with natural extractives providing inherent resistance to decay and insect attack without reliance on chemical preservatives. The three-layer door jamb construction refers to engineered lamination of stiles and rails, typically cross-banded or finger-jointed for dimensional stability in varying humidity conditions. The listing specifies an anti-slip finish on decking surfaces, though the precise profile pattern (grooved, ribbed, or sanded) and treatment chemistry remain unstated.

The material properties of Balau and Bangkirai support exterior applications where lesser species would fail. Bangkirai typically presents a dry density of 850-1100 kg/m³ with durability class 1-2 (BS EN 350-1), comparable to teak in ground-contact performance. Balau species vary by origin but generally fall within 800-1000 kg/m³ with similar natural durability. For three-layer door jambs, the lamination technique mitigates the radial and tangential shrinkage differential (typically 5-8% tangential, 2-3.5% radial for these species) that causes solid timber to warp. The anti-slip treatment mentioned likely involves surface profiling rather than applied coating, as film-forming finishes on exterior hardwoods often fail through UV degradation and peeling.

Buyers for this product range include landscape architects specifying premium decking for residential poolsides and commercial boardwalks, door and window manufacturers requiring stable jamb components, and construction firms building in tropical or coastal environments where salt and humidity accelerate deterioration of softer timbers. The listing notes manufacturer-direct sourcing with competitive pricing and customisable MOQ, though exact quantities, price bands, and current availability require direct negotiation. FOB and CIF shipping terms are mentioned without specifying ports or Incoterm editions. No lead time, sample policy, or warranty terms appear in the source material.
