Is Haichen Stone a granite manufacturer or a trading company?

We are a manufacturer. Rizhao Haichen Stone operates its own quarry reserves and processing workshop in the Rizhao Stone Industrial Park, Shandong, and holds independent import-export rights, so buyers work directly with the producer.

Which granite finish should I specify for exterior paving?

For outdoor pedestrian areas we normally recommend flamed or bush-hammered granite in 30 mm or thicker. Vehicular areas require thicker sections designed by the project engineer. Polished granite is best reserved for interior walls and dry indoor areas.

How do you control granite quality before shipment?

Quality control starts with block selection at the quarry, followed by size and thickness tolerance checks, colour matching under daylight, dry-lay for key projects, and pre-shipment photos or video. Buyers are welcome to appoint third-party inspectors.

Which port do you ship from and how is the stone packed?

Our factory is close to Rizhao Port, with Qingdao Port as an alternative. Products are packed in fumigated wooden crates or bundles suitable for sea freight, and common Incoterms such as FOB and CIF can be discussed with our trade team.

Can I visit the factory or quarry before ordering?

Yes. We welcome buyers, architects and inspectors to visit our quarry and processing workshop in Rizhao. Contact our team to arrange a visit date.

Besides granite, what building materials can you supply?

In addition to granite slabs, paving, kerbs and carving, we supply steel structures, glass clamp fittings and door and window systems, which allows project buyers to consolidate several packages with one supplier.

Strategic Procurement Engineering

Global Procurement Imperatives & Structural Solutions

Wholesale buyers across the automotive, maritime, and specialized building sectors face complex regulatory, optical, and mechanical hurdles. Our consolidated engineering workflow bridges precision fabrication and long-term durability.

Interlayer Structural Integrity

Utilizing high-performance Polyvinyl Butyral (PVB) and SentryGlas (SGP) interlayers ranging from 0.76mm to 2.28mm thickness, our laminated windshield configurations eliminate edge delamination risks under persistent thermal cycling (-40°C to +95°C) and UV degradation.

Optical Distortion Elimination

Critical for autonomous driving calibration (ADAS) and high-speed pilot visual fidelity, our gravity and press-bending furnaces utilize dual-axis laser verification to guarantee curvature deviation under <0.5mm across complex asymmetric profiles.

Turnkey Envelope Integration

Beyond glass, our industrial platform unifies curtain-wall subframes, stainless glass clamp fittings, and structural steel channels, resolving supply chain fragmentation for major contractors requiring bundled envelope materials.

Technical Clarifications

Frequently Asked Technical Questions (FAQ)

Detailed insights regarding manufacturing capabilities, testing tolerances, and custom development lifecycles.

What is the standard lead time for custom windshield toolings and prototypes?

Tooling design, CNC ceramic mold manufacturing, and initial sample production typically require 20 to 30 calendar days. Full pilot production and optical scanning certification are delivered within 10 days post-mold approval.

How is optical quality verified for vehicles equipped with forward-facing cameras?

We employ transmission distortion projection tables and multi-camera optical inspection systems in our cleanroom environments to detect refractive anomalies in the primary camera sweep zone (Zone A), guaranteeing compatibility with Level 2+ ADAS calibration.

Can you provide combined shipments containing both glass systems and cladding materials?

Yes. Leveraging our vertically integrated facilities and logistics hubs, we provide mixed-container consolidation combining laminated glass assemblies, steel clamps, stone facade panels, and structural framework to optimize freight expenditure.

What testing procedures are implemented for ballast and impact resistance?

Our on-site QA lab conducts continuous 227g steel ball drop tests from 10 meters, phantom head-form impact simulations per ECE R43, and 1000-hour boil tests to guarantee absolute zero bubble formation or interlayer separating tendencies under stress.
