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.

Premium grades may exhibit subtle, understated veining that enhances sophistication without appearing jarring or chaotic. Its basaltic composition yields tighter grain patterns, delivering superior abrasion and scratch resistance. This defines its core identity for premium gravestones and high-end exterior cladding, enabling instant visual differentiation from other black granite varieties.

Compared to G654 (Sesame Black)/G3401 (Shanxi Black): G684 (Fuding Black) presents a pure black surface without impurities, featuring a basaltic texture. G654 exhibits a deep grey-black base with white sesame-like specks, resulting in a markedly different textural identity. G3401 is a premium pure black granite (with brighter colouration and higher pricing). G684 exhibits superior resistance to seawater corrosion, making it suitable for coastal projects. Its cost-effectiveness positions it between G654 and G3401, catering to mid-to-high-end export markets as a high-value alternative to imported black granites.

Gloss: Polished surfaces achieve ≥90° gloss, delivering mirror-like brilliance with deep, translucent black tones—ideal for premium interiors and memorials. Flamed/bush-hammered finishes present uniform matte jet black without discolouration, offering slip resistance, substantial texture, stain resilience and easy maintenance. These surfaces are the preferred choice for outdoor projects, with both treatments catering to diverse overseas applications.
