Poland — Strzegom Granite, Polish Grey, Schönwald Syenite

Core Strengths

• Strzegom granite, scale and stability: the Lower Silesia quarries have a long mining history, large block sizes and stable output, ideal for public works and facades needing large same-batch volumes.
• Polish Grey, versatile and forgiving: even light-to-mid grey with fine speckling that combines easily with other materials, suited to plazas, floors and counters.
• Schönwald syenite, dense and composed: a fine-grained dark grey-green syenite gneiss with high hardness and an excellent polish, suited to counters, sills and high-traffic floors.
• Mature EU-standard supply chain: Polish quarries supply slabs to EN 12057 / 12058 and PN standards, shipped via Gdańsk or Hamburg with mature scheduling and batch traceability.

Key Figures

Service Process

1. Use confirmed: colour and finish chosen for plaza, facade, floor or counter.
2. Ground tone checked: grey depth, speckle distribution and spotting tolerance verified.
3. Block inspection: hidden-crack detection and colour grading, then numbered into storage.
4. Processing and protection: calibrated, finished, then six-face protection applied.
5. Shipping: loaded at Gdańsk or Hamburg for ocean freight to Hong Kong or Foshan.

Applications

• Plazas, footways and kerbstone for public paving
• Building facades and sills
• High-traffic floors and counters
• Contemporary grey walls and floors

Sustainability & Certification

Polish quarries operate under EU mining directives; partner quarries hold ISO 14001 certification, with pit restoration and offcut use reviewed annually.

Polishing granite uses a good deal of water, so the plant recirculation system carries it and recovers the grinding slurry, with offcuts sorted for construction aggregate.

Deep Selection Guide

The priorities with Polish granite are batch uniformity and the surface finish: large projects should use batch locking and reserve the full quantity including wastage in one order, so later top-ups do not differ in tone. For outdoor work confirm the slip class and freeze-thaw performance, and specify where flamed, bush-hammered or honed finishes apply in the project documentation; polished faces for counters and interiors are maintained day to day with a neutral cleaner.

• Selection criteria：Starting from public paving and building facades, settle the stone type and thickness first, then check grey tone and speckle consistency.
• Specification & thickness：Dimension and thickness follow the 3 core Polish varieties, with EN tolerance, slip and protection requirements noted for outdoor elements.
• Acceptance & records：Verify the tone and crystal of Strzegom granite item by item and accept on site by number; the batch code traces back to production and testing data.
• Sustainability：Polish quarries operate under EU mining directives with ISO 14001 coverage; include this in acceptance documents and align with local green-building requirements.

FAQ

Does Polish granite suit Hong Kong projects?

Yes. Polish granite is low in absorption, abrasion-resistant, weatherproof and even in tone, performing reliably on outdoor plazas, sills and facades in Hong Kong. Outdoors choose flamed or bush-hammered finishes with six-face protection; indoor floors and counters can take a polished finish with neutral-cleaner maintenance.

How is batch variation controlled on large projects?

Through batch locking with sealed physical slabs: confirm ground tone range and speckle distribution before ordering, reserve the block batch at the start and number slabs by layout, supplying from one batch throughout. For large areas reserve the full quantity including wastage so later top-ups do not differ in tone.
