The pre-sales, in-sales and after-sales services of aluminum solar panel frame are the key links in our cooperation with you, which directly affect our decision-making and project execution efficiency. The following is a summary of the specific service content:

Pre-sales Service

Professional technical consultation and product matching

Provide material analysis (such as aluminum alloy model 6063-T5/T6), surface treatment process (anodizing, sandblasting, etc.) and weather resistance data.
Recommend frame cross-section design according to your photovoltaic module size (such as conventional 33/45mm or customized requirements) to ensure structural strength and installation compatibility.
Answer performance indicators such as load capacity (such as wind pressure resistance, snow load), corrosion resistance (salt spray test standard).
Scheme design and optimization

Assist in designing lightweight frames (reducing aluminum usage and saving costs), or reinforcement solutions (for high wind pressure areas).
Provide CAD drawings, 3D models and tolerance recommendations to match the installation requirements of automated production lines.
Sample support and test verification

Send samples for customer testing free of charge, and provide third-party test reports (such as TUV, UL certification).
Support customers to conduct component packaging adaptability tests to ensure the compatibility of the frame with glass and EVA film.
Cost analysis and quotation strategy

Provide floating pricing or fixed price lock solutions based on the fluctuations of aluminum ingot futures prices.
Analyze cost optimization suggestions such as bulk order discounts and mold fee sharing (for non-standard products).
Case reference and risk prediction

Share similar project experience (such as anti-sand erosion design of desert power stations and anti-corrosion solutions for coastal projects).
Early warning of common problems (such as transportation deformation and installation hole deviation) and provide avoidance measures.

In-sales Service

Order management and production follow-up

Real-time synchronization of production scheduling (such as extrusion, cutting, CNC processing nodes), and regular production progress reports (with workshop photos/videos).
Coordinate expedited orders (such as plug-in production) to ensure delivery cycle (conventional 15-20 days, expedited 7-10 days).
Quality control and inspection support

Provide IPQC (process inspection) report, key indicators such as dimensional tolerance (±0.5mm), angle deviation (±1°), surface defects (scratches ≤0.1mm).
Support customers or third-party organizations (such as SGS) to inspect the goods at the factory, and provide full inspection or sampling plans.
Logistics coordination and risk plan

Recommend transportation methods (sea freight/bulk cargo, land transportation dedicated line) according to customer location, calculate freight and insurance costs.
For fragile packaging (such as corner protection), provide reinforcement solutions and track logistics tracks until receipt.
Technical collaboration and on-site support

Remotely guide the installation team (such as torque value setting, splicing seam processing), and dispatch engineers to debug on site when necessary.
Provide installation video tutorials, operation manuals and FAQ quick checklists.

After-sales Pre-connection

Report after-sales contacts in advance and explain the warranty terms (such as 45-year warranty scope).
Reserve spare parts (such as 1-2% of order volume) to meet emergency replenishment needs.

Supplier Selection Recommendations
Qualification Verification: Confirm ISO 9001, ISO 14001 system certification and photovoltaic industry-specific certification (such as CQC).
Capacity Assessment: Inspect the tonnage of the extruder (such as above 1800T) and the length of the oxidation line (affecting the uniformity of surface treatment).
Cooperation Cases: Require a list of cooperative customers in the past year (especially similar projects) to verify delivery stability.
Response Efficiency: Test the pre-sales response speed (such as replying to technical consultation within 24 hours) and evaluate service awareness.
