Do you ship entry doors to Nigeria, Ghana, Kenya and South Africa?

Yes. We export by sea container and can quote FOB China or CIF to major African ports such as Lagos (Apapa / Tin Can), Tema, Abidjan, Mombasa, Dar es Salaam and Durban. Doors are export-crated individually to prevent transit damage.

Which entry door material is best for coastal African cities like Lagos, Mombasa or Durban?

For salt-laden, humid coastal air we usually recommend stainless steel doors or aluminum doors with a high-durability powder coating or fluorocarbon finish, combined with stainless steel hinges and fasteners and EPDM seals. Final specification depends on distance from the sea and exposure.

Can you manufacture custom sizes for villa main gates and large pivot doors?

Yes. Every door is made to order. Our engineering team prepares CAD shop drawings based on your opening sizes, swing direction, hardware, glass and finish so the door matches your architectural drawings before production starts.

What certifications do your doors have, and can you support import documentation?

Our product range holds certifications including CE, ISO9001, AS2047 and UL fire-rated listings for applicable models. We can provide test reports, packing lists and commercial documents that your clearing agent may require for national conformity programs.

How do I get installation support if my project is in Africa?

Each order ships with installation drawings and manuals, and our English-speaking engineers provide remote guidance by email and video call during installation and after handover.

What information should I send to start an entry door project?

Send opening sizes (width x height), quantity, preferred material and style, glass and lock requirements, project location and destination port to info@derchiafrica.com. Architectural drawings or site photos help us respond faster and more accurately.

Procurement Insights

Future Procurement Trends in Aluminium Interior Doors

Navigating global structural transitions, carbon tax regulations, and technical compliance in high-volume fenestration procurement.

Low-Carbon Profile Demand

Global procurement teams prioritize circular economies. Demands for billets cast via green hydroelectricity are shifting specifications across high-tier developments seeking LEED and BREEAM certifications.

Single-Source Factory Consolidation

Procurement departments are bypassing fragmented sourcing. Contractors demand integrated manufacturing that coordinates interior swing doors, thermal partitions, and exterior entries under a single QC audit framework.

Stringent Code & Acoustic Verification

Mockup testing compliance is no longer optional. Sourcing criteria mandate verified laboratory reports covering acoustic STC ratings, UL smoke-spread mitigation, and structural wind-load deflection metrics.

R&D Evolution

Technological Advancements in Aluminium Interior Systems

Discover how metallurgy, mechanical hardware, and minimalist engineering redefine the modern interior door envelope.

Slim Sightlines & Concealed Hardware

Modern interior aesthetics rely on ultra-narrow stiles (less than 20mm visible frame) coupled with structural structural-glazed adhesive bonding and German 3D adjustable concealed hinges.

Acoustic Decoupling Engineering

Multi-chamber aluminium extrusions injected with acoustic resin foams, paired with continuous vulcanized EPDM gaskets and drop-down automated threshold seals, achieve sound attenuation up to STC 42.

Advanced Anodization & Fluorocarbon Tech

Electrophoresis and multi-stage PVDF fluorocarbon coatings resist high humidity, saline air, and intensive chemical cleaning regimens without micro-cracking, fading, or edge degradation.

Procurement Guidance

Frequently Asked Technical Questions

Common inquiries from architectural procurement managers, project distributors, and commercial contractors.

What aluminum alloy grade and profile wall thickness do you specify for interior doors?

We use virgin architectural 6063-T5 aluminum alloy billets. Depending on the door series and height specifications, our profile wall thicknesses range from 1.4mm to 2.2mm for standard interior swing applications, and up to 3.0mm for heavy-duty pivot and sliding systems. This profile structure avoids sagging and maintains square tolerances across extended service cycles.

How does your factory verify sound insulation and air-permeability performance?

Our products undergo comprehensive chamber testing evaluating air leakage according to ASTM and EN benchmarks. Acoustic performance is achieved through engineered hollow-core chambers, insulated perimeter EPDM co-extruded gaskets, and insulated safety glass modules (such as 6mm + 12A + 6mm double glazing or laminated acoustic PVB panels) that reduce interior sound transmission significantly.

What certifications can DERCHI supply for customs clearance and architectural sign-off?

We provide full documentation packs tailored to project regions, including ISO9001 Quality Management verification, CE declarations of performance, AS2047 acoustic and wind-load certified test reports, and UL safety certifications for fire-rated models. In addition, we coordinate pre-shipment third-party inspections (SGS, TÜV, Intertek) based on customer requirements.

What is the standard production cycle and minimal order quantity (MOQ) for custom projects?

For project orders with customized dimensions, finishes, and hardware preparations, our typical production lead time is 25 to 35 business days following CAD shop drawing approval. We accommodate mixed-container schedules with manageable MOQs, allowing commercial developers to consolidate interior doors, entrance systems, and partition units into single container shipments.

How do you ensure door frames arrive without scratches or diagonal distortion?

All frame jambs and leaf profiles are covered with protective electrostatic film, wrapped in shock-absorbent EPE foam, and corner-shielded with heavy-gauge composite protectors. Sub-assemblies or knocked-down (KD) packages are secured inside reinforced, heat-treated plywood crates engineered with internal bracing to prevent shift and racking during ocean transport.
