Cumaru Decking (CUMARU-A) — 21x145x3600mm

Description

1. Product Overview

Cumaru Decking (CUMARU-A) — 21x145x3600mm is a premium, tropical hardwood decking board milled to commercial-grade dimensions for heavy-duty exterior decking and structural timber applications. Engineered from dense Cumaru species, it delivers exceptional hardness, natural resistance to decay and insects, and long-term dimensional stability in exposed environments. Its primary industrial use is for large-scale outdoor decking, boardwalks, marine-side terraces, and commercial landscaping where durability and low lifecycle maintenance are mission-critical. Strategically, Cumaru combines superior longevity and low total cost of ownership versus treated softwoods and many composite alternatives, making it a high-value, long-run sourcing choice for contractors, developers, and infrastructure buyers.

2. Key Specifications & Technical Characteristics

• Material: Solid Cumaru (undifferentiated Dipteryx spp.), kiln-dried and finished

• Grade: CUMARU-A — commercial grade boards with select appearance and structural integrity suitable for heavy traffic environments

• Dimensions: nominal 21 mm thickness x 145 mm width x 3600 mm length per board

• Density / Specific gravity: typically 0.85–1.05 g/cm³ (air-dry), high mass yield for load-bearing decking

• Hardness: Janka hardness ~3,500–4,400 lbf (species dependent), significantly higher than common hardwoods used in decking

• Moisture content: kiln-dried to 10–15% target at dispatch (stabilized for exterior use)

• Surface finish: planed with smoothed face; available in unfinished or pre-oiled options on request

• Durability: Class 1 heartwood durability (very durable), natural rot and termite resistance

• Color / appearance: rich amber to reddish-brown when fresh, weathers to silver-gray patina if left untreated

• Tolerances: dimensional mill tolerances ±1.0 mm thickness, ±1.5 mm width, ±5 mm length

• Packaging: bundled on pallets, banded and shrink-wrapped; non-stack or container-stowage protective dunnage available

• Standard pallet contents: configurable per order (see Commercial & Supply Information)

• Shelf life: indefinite when stored dry and ventilated; recommended indoor covered storage to maintain moisture content and avoid surface checking

3. Core Industrial Applications

• Commercial and municipal decking: boardwalks, public promenades, outdoor dining decks, and plazas where heavy foot traffic and durability are required. Cumaru’s high hardness reduces wear and long-term maintenance costs compared with softwood alternatives.

• Marine and waterfront structures: docks, piers, and marina walkways benefiting from Cumaru’s natural resistance to marine borers and decay, extending service life in saline and wet environments.

• Landscape and urban infrastructure: plazas, steps, seating, and cladding where dimensional stability and aesthetic longevity reduce replacement cycles.

• High-end residential and hospitality projects: premium terraces, pool surrounds, and façade elements where natural appearance and tactile quality matter.
  Why it outperforms alternatives: Cumaru’s high density and natural durability provide superior scratch, dent, and biological resistance compared with pressure-treated softwoods and many composites, lowering lifecycle maintenance and replacement frequency. It delivers a favorable durability-to-cost ratio for projects prioritizing long-term asset value.

4. Competitive Advantages

• Quality consistency: factory-controlled kiln drying and machine milling ensure uniform dimensions, moisture content, and surface finish across bulk shipments.

• Supply reliability: established sourcing channels and bulk inventory management support scheduled deliveries for large projects and phased rollouts.

• Logistics capability: packed for containerized export, with experienced handling protocols to minimize damage and moisture variation; export documentation and customs support available for major trade lanes.

• Price competitiveness: premium durability and extended service life translate into lower total cost of ownership compared with frequent-replacement softwoods and some low-grade composites. Volume pricing available for contractual offtake.

• Sustainability: responsibly sourced from suppliers providing traceability; documentation of origin and compliance certificates (where available) can be provided to support procurement sustainability requirements.

• Technical support: product datasheets, installation guidelines, maintenance recommendations, and project-specification assistance available for engineering and procurement teams.

5. Commercial & Supply Information
