Resin Grinding Discs & Diamond Polishing Pads Sourced from Verified China Factories
Product Overview
SourcingProChina is a sourcing agent based in China. Through our network of vetted manufacturing partners specializing in abrasive tooling, we help overseas buyers procure resin grinding discs used in the fine grinding and polishing stages of floor preparation. These pads are engineered to remove scratches left by metal-bonded tools and deliver a high-gloss finish on concrete, terrazzo, and stone surfaces. We coordinate sourcing for both dry and wet grinding disc types, and manage factory selection, sample testing, quality control, and export logistics on the buyer's behalf.

Frequently Asked Questions (FAQs)
Is SourcingProChina a manufacturer or a sourcing agent?
SourcingProChina is a sourcing agent based in China. We do not own factories; instead, we identify, vet, and manage relationships with qualified manufacturers on behalf of overseas buyers, and oversee quality control, sampling, and shipping logistics.
What is the difference between dry and wet resin discs?
Dry discs are formulated to withstand higher temperatures generated during dry grinding without water lubrication. Wet discs are used with water, which cools the pad and often produces a finer surface finish — our sourcing team can help match the correct type to your job site conditions.
How many grits do I need to polish a concrete floor?
A typical grinding sequence starts at 50# or 100# to remove scratches, then progresses through 200#, 400#, 800#, up to 1500# or 3000# for a high-gloss finish. We can source a full grit set matched to your target sheen level.
Can these discs fit my existing floor grinder?
Sourced discs are available in standard sizes (80mm, 100mm) with common mounting types (5-hole, single pin). Share your machine model with us and we will confirm compatible factory options.
What does a "physical polish" pad do?
A physical polish pad produces a high-gloss finish through friction and pressure alone, without separate chemical polishing powders or liquids — reducing material costs and simplifying the polishing process for your crew.
How long do the resin discs last?
Lifespan depends on floor hardness and applied pressure. Based on factory-reported data, a set typically covers 2,000–5,000 square meters depending on grit and application; we can request factory test reports for your specific use case before you commit to bulk ordering.
How does sourcing through an agent differ from ordering directly from a factory?
As your sourcing agent, SourcingProChina performs factory audits, negotiates on your behalf, consolidates orders across multiple suppliers if needed, and manages quality inspection — reducing the risk of dealing with unverified manufacturers directly, especially for first-time buyers unfamiliar with the China supply chain.
