Reclaimed Ulin Battens, Joists & Rafters Bali, Indonesia
Four standard reclaimed Ulin batten profiles plus custom joists and rafters manufactured in Bali for architectural, structural and outdoor timber projects.
Standard battens. Custom joists and rafters.
Naturanexa keeps the standard range intentionally simple: four practical reclaimed Ulin batten profiles. Joists, rafters and all non-standard batten dimensions are produced according to project requirements.
Horizontal support framing for floors, platforms, subframes and project-specific structural assemblies.

Three components
three different functions
The distinction is important because the same timber species can perform very different roles within a building.
Battens
Smaller repeated timber sections used for screens, architectural slats, lighter framing and linear details.
Joists
Horizontal repeated support members used below floors, platforms and other timber substructures.
Rafters
Repeated roof members that can remain structural only or become visible within exposed timber architecture.
Where battens, joists and rafters are used.
Reclaimed timber selected and processed
for repeated components
Reclaimed timber naturally arrives with dimensional variation. Naturanexa selects suitable Ulin stock and processes it toward the repeated sections required for battens, joists and rafters.
This is especially important when multiple components need to align visually or form part of the same structural system.
What we need from you.
Standard battens are simple. For custom battens, joists and rafters, send these four pieces of information so we can review the project efficiently.
Battens, joists and rafters explained.
Open only the questions relevant to your project.
What is the difference between a batten, a joist and a rafter?
Battens are smaller repeated timber sections typically used for slats, screens and lighter framing. Joists are repeated horizontal support members used beneath floors or platforms. Rafters are repeated members within roof structures.
What standard Ulin batten sizes does Naturanexa offer?
Naturanexa offers four standard reclaimed Ulin batten profiles: 2 × 3 cm and 3 × 4 cm for indoor or sheltered applications, and 3 × 5 cm and 4 × 6 cm for outdoor or exposed applications.
Can Naturanexa manufacture other batten sizes?
Yes. Any batten dimension outside the four standard profiles is treated as custom production and quoted according to section, length, quantity and available reclaimed stock.
Are Ulin joists available in standard sizes?
Joists are treated as project-specific components rather than one universal standard size. Send the required section, lengths and quantities for review.
Are Ulin rafters available in standard sizes?
Rafters are manufactured according to project requirements. Send the required section, length, quantity and relevant drawings where available.
Can reclaimed Ulin be used for exposed rafters?
Yes. Reclaimed Ulin rafters can remain visible where the timber roof structure forms part of the architectural design.
Which standard batten sizes are intended for outdoor use?
Naturanexa's standard outdoor profiles are 3 × 5 cm and 4 × 6 cm. Final suitability still depends on the specific application, spacing, fixing method and design.
Can Naturanexa work from drawings or a BOQ?
Yes. Drawings, BOQs and component schedules are useful for defining custom joists, rafters and other project-specific timber sections before quotation and production.
Does Naturanexa determine the structural size required?
Naturanexa manufactures components to agreed dimensions. Structural sizing, spans and loads should be determined by the project's architect, engineer or qualified professional.
Where are the components manufactured?
Naturanexa selects and processes its reclaimed Ulin battens, joists, rafters and structural components in Bali, Indonesia.
Where should I go for reclaimed Ulin decking or flooring?
Reclaimed Ulin decking and flooring are the specialist focus of our sister company Kaltimber. Naturanexa focuses on structural timber, battens, joists, rafters, building components, outdoor elements and architectural joinery.
Need reclaimed Ulin battens, joists or rafters?
Choose one of our four standard batten profiles or send the dimensions, lengths, quantities, drawings or BOQ for custom battens, joists and rafters.
