Q1
What are the exact structural alloy grades and extrusion tolerances used in your aluminium grill doors?
We utilize primary 6063-T5 and high-tensile 6063-T6 architectural aluminium alloy billets. Extrusions adhere strictly to ISO 2768-m and EN 12020-2 precision tolerances. Profiles feature engineered internal web ribs and wall thicknesses ranging from 1.4mm to 2.5mm, ensuring zero deflection under severe structural wind loads (up to 3000 Pa for AS2047 compliance).
Q2
How does your factory accommodate custom (ODM) profile development and die extrusion costs?
For specialized architectural profiles or proprietary dealer systems, our tooling department designs and cuts custom steel extrusion dies within 10 to 15 business days. Tooling charges are fully refunded to the buyer once cumulative order volume reaches an agreed threshold (typically 10 to 15 metric tons of extruded aluminium).
Q3
What anti-corrosion test standards do your powder coating and anodized surface finishes meet?
Our PVDF fluorocarbon (70% Kynar 500) coatings comply with AAMA 2605 and endure over 2,000 hours of Neutral Salt Spray (NSS) testing without blistering or color shifting. Powder coatings meet Qualicoat Class 2 standards, while anodized finishes achieve AAMA 611 Class I (film thickness ≥ 18 microns), ensuring decades of service in harsh marine environment exposures.
Q4
Can your aluminium grill doors comply with specific national building codes like AS2047, NZS4211, or Miami-Dade?
Yes. Our product lines hold verified independent laboratory test certificates. We provide AGWA accredited compliance certificates for Australia (AS2047:2014, AS1288:2021, NCC 2022), New Zealand Building Code certificates (NZS4211:2008 clauses B1, B2, E2, F2, G4, G7, H1), North American NAFS test reports, and Miami-Dade County TAS 201/202/203 missile impact test approvals.
Q5
What types of security grills and insect screens can be integrated into the door frames?
We supply three main screen options: (1) High-tensile 304 or 316 marine-grade stainless steel woven security mesh (0.80mm wire diameter, 11x11 mesh count) passed shear and knife-shear impact tests; (2) Heavy-gauge expanded aluminum grill patterns; and (3) Ultra-fine fiberglass or stainless steel insect screens with quick-release magnetic tension frames.
Q6
What is the standard production lead time and minimum order quantity (MOQ)?
Standard production lead time is 35 to 50 calendar days following shop drawing sign-off and deposit receipt. For standard profile systems in stock RAL colors (Black, White, Anthracite Grey), our MOQ starts at 20 square meters (or 1 full project unit schedule). For bespoke profile extrusions, MOQ depends on billet die minimums (typically 500 kg per profile shape).
Q7
What technical support and shop documentation are included prior to production?
Every order includes comprehensive engineering deliverables: full AutoCAD elevation schedules, 1:1 scale profile cross-section drawings, sill/jamb/head detail installation drawings, glass performance calculations, and hardware layout schematics to ensure smooth certifier approval and straightforward jobsite installation.
Q8
What glass specifications are paired with your security grill doors?
We offer double or triple insulated glass units (IGUs) incorporating toughened safety glass (BS6206 / AS2208 certified), Low-E soft coatings, warm-edge spacers, and Argon gas fill. For storm and acoustic applications, we integrate PVB or SentryGlas (SGP) laminated safety glass up to 21.52mm total thickness.
Q9
How are products packaged to prevent freight damage during container ocean transport?
Doors undergo a 5-layer protective packaging procedure: (1) PE protective film over aluminium profiles; (2) Foam corner caps; (3) Heavy bubble-wrap sheeting; (4) Corrugated cardboard outer wraps; and (5) Fully enclosed fumigated ISPM-15 plywood wooden crates loaded onto custom steel A-frames for forklift handling.
Q10
What warranty terms do you provide for commercial project procurement?
We back our products with a standard 10-Year Quality Assurance Warranty covering structural aluminium extrusion integrity, profile powder coating adhesion against peeling, and glass seal performance against internal condensation, alongside a 5-year replacement warranty on multi-point locking hardware mechanisms.
