Procurement Intelligence
Frequently Asked Questions by Indonesian Importers & Contractors
Expert answers addressing the legal, financial, technical, and logistic requirements when procuring factory-direct aluminium partition systems and sliding doors from China to Indonesian job sites.
Q1
How do your aluminium partitions and doors comply with Indonesian SNI and Building Codes?
Our aluminium profiles are manufactured from primary virgin 6063-T5/T6 billet conforming to strict mechanical tolerances equivalent to SNI 07-0603. For facade and fenestration installations, our systems meet the dynamic wind pressure guidelines established by SNI 03-1727 and seismic drift tolerances outlined in SNI 03-1726. Our engineering division furnishes localized laboratory test certificates, wind deflection calculations, and factory mill analysis certificates alongside each containerized shipment.
Q2
What surface treatments are recommended for coastal resort applications in Bali and Lombok?
For installations situated within 3 kilometers of the shoreline, we mandate high-durability Qualicoat Class 2 / AAMA 2605 certified PVDF fluorocarbon coatings (minimum 3-coat system, 35-micron thickness) or Marine-Grade Anodizing (minimum 25-micron coating thickness). Standard commercial powder coating tends to develop filiform corrosion in warm tropical maritime conditions; our marine-spec finishing withstands up to 3,000 hours of continuous neutral salt spray testing without micro-pitting or color degradation.
Q3
What are the typical sea freight lead times and destination ports for Indonesian deliveries?
Ocean freight transit from the Nansha or Shekou container ports in Guangzhou/Shenzhen to Tanjung Priok (Jakarta) or Tanjung Perak (Surabaya) typically spans 7 to 10 days. Shipments destined for Batu Ampar (Batam) require roughly 4 to 6 days, while direct feeders to Benoa (Bali) or Balikpapan (for IKN Nusantara) run approximately 12 to 16 days. Our standard manufacturing cycle requires 25 to 35 days following formal CAD shop drawing sign-off and deposit receipt.
Q4
Can DERCHI supply complete knock-down (CKD) or fully assembled units for fast site installation?
We provide both configurations based on contractor preference and freight efficiency. For high-volume multi-story developments, CKD (Complete Knock Down) profile kits maximize container cube capacity, with pre-notched profiles, pre-machined lock recesses, pre-drilled assembly holes, and pre-cut EPDM gaskets. For luxury residential and hotel suites requiring flawless factory precision, we provide Fully Assembled glazed frames, crated in fumigated solid plywood cases for immediate site hoist and drop-in anchoring.
Q5
How does your export packaging prevent moisture damage and glass breakage during tropical transit?
Given the extreme relative humidity encountered in tropical equatorial shipping routes, every extrusion undergoes a five-layer protection protocol: protective low-tack PE film on profile surfaces, wrapped in closed-cell EPE pearl foam, interleaved with desiccants, packaged in waterproof multi-wall corrugation, and braced inside IPPC ISPM-15 heat-treated, fumigated timber crates. Glass panels feature impact corner bumpers and steel-strapped A-frames to prevent flexing in heavy sea states.
Q6
What hardware brands and warranty terms are provided with sliding partition systems?
We equip our sliding partition systems with globally reputable German hardware configurations (such as Siegenia, Hoppe, or GU) as well as premium heavy-duty DERCHI proprietary architectural systems. Rollers feature sealed SUS316 stainless needle bearings tested up to 200,000 continuous opening cycles under maximum glass loads. We back our extruded aluminium profiles with a 15-to-25 year structural warranty and our architectural operating hardware with a 5-year replacement warranty.
