SGL SOLUTION
Technical support built around drawings, climate and long-term
maintenance
The client focused on cost, technical reliability, warranty risk and local compliance. SGL responded
with multiple configuration options and clarified each key decision point.
Drawing and schedule review
The team checked window and door tables against drawings, clarified frame size, wall-to-wall size, opening direction, quantity conflicts and changed balcony closures.
High-rise wind-load configuration
For a 20-story building in a strong-wind area, SGL discussed reinforced steel, reinforced mullions, closer fixing spacing, stronger installation plates and sealing details.
System options and price comparison
The quotation process covered Gaoke 72 series, CONCH 70 series, aluminum thermal-break systems, Kinlong hardware, optional OTA hardware and fire-rated door alternatives.
Glass and safety requirements
The project discussion covered Xinyi glass, Low-E insulated glass, all-tempered glass, child safety locks, fire-rated glass positions and custom formulas from the client's table.
Factory transparency
SGL answered trust concerns with manufacturer credentials, factory videos, production process explanation, quality control flow and a customer visit arrangement in China.
Logistics and installation planning
The team prepared approximate packing data, customs code categories, weight, volume, crate count and a one-month installation planning discussion for the project site.
COMMUNICATION HIGHLIGHTS
Careful clarification before price confirmation
The customer's questions were highly technical. Instead of providing a single quick price, SGL helped compare alternatives so the client could report internally and evaluate total project risk, not only unit cost.
- Reviewed the difference between 70, 72, 85, 93 and 110 series configurations.
- Explained why high-rise wind pressure requires stronger reinforcement and installation details.
- Separated uPVC, aluminum and glass values for customs and logistics calculation.
- Discussed spare parts reserve and after-sales service wording for the contract.
- Provided contract samples for both uPVC and aluminum options for legal review.

SERVICE PROCESS
Project Timeline
Five months of deep technical engagement from first inquiry to contract drafting
Initial Inquiry
First contact via Facebook/WhatsApp. Architectural drawings and specifications shared. Discussion began with own-house project before expanding to full residential complex.
Technical Clarification
Multiple rounds of glazing formulas, profile chambers, fire ratings, and hardware brands. Four versions of quotations prepared with trust & credibility package.
Optimization & Factory Visit
Price optimization rounds, smart-lock discussions, door cross-sections. Client visited Xi'an factory. Full-aluminum option introduced. Contract drafts prepared.
Final Technical Alignment
Hardware brand comparisons (OTA vs Kinlong), 2.5mm aluminum inquiry, updated window tables with additional closed-loggia units. Three-way HS-code cost split delivered.
Contract Stage
The finalized draft contracts for the PVC (¥2.55 million) and Aluminum (¥3.30 million) bid packages have been dispatched. These are now pending internal client approval and the transfer of funds from the investor.
