What is the difference between LVT and SPC flooring?

LVT (luxury vinyl tile) uses flexible PVC layers and is usually glue-down or click installed, offering a softer, quieter feel. SPC (stone plastic composite) has a rigid core made of limestone powder and PVC, which gives higher dimensional stability, full waterproof performance and a floating click-lock installation over most existing hard floors.

Do you provide samples before a bulk order?

Yes. Samples are available so buyers can check color, surface texture, thickness and click profile before confirming a bulk order. Contact our sales team with your target specification and destination.

What is your typical delivery time?

With eight production lines located near major ports, standard orders are typically dispatched within 7 to 15 days after order confirmation. Exact lead time depends on specification, customization and order volume.

How can I check the quality of PP hollow plastic formwork?

Compare panel weight per sheet for the same thickness, inspect surface flatness and rib structure, and ask for performance under heat and cold. Low-grade panels tend to warp or show wave-like deformation in summer and crack in winter. Our blog explains simple on-site tests.

Can you produce custom designs and private-label packaging?

Because we integrate product development, design and production, we can discuss custom decors, colors, thickness, sizes and packaging according to your market and order quantity.

Critical Technical Insight: Limestone-to-Resin Ratio Optimization

In low-grade SPC plank production, manufacturers over-pack calcium carbonate (CaCO3) up to 4.5:1 ratio to cut costs, making the click profile brittle and prone to snapping during installation. Greenstar maintains a strict 3.0:1 to 3.2:1 ratio using 100% virgin PVC resin, providing optimal flexibility, superior impact strength (EN 433 compliance), and long-term click-joint integrity.

Procurement Knowledge Base

Frequently Asked Questions (B2B Sourcing FAQ)

In-depth responses from our senior engineering team to common procurement, manufacturing, and logistical inquiries.

What is the structural difference between SPC vinyl plank and LVT vinyl flooring?

LVT (Luxury Vinyl Tile) is constructed from flexible PVC layers, making it softer, quieter underfoot, and typically installed via direct glue-down or light click systems. However, LVT requires a perfectly flat subfloor to prevent telegraphing. SPC (Stone Plastic Composite) features a rigid core composed of natural limestone powder (CaCO3) and virgin PVC resin, yielding a density above 1900 kg/m³. SPC is 100% waterproof, dimensionally stable against temperature spikes, and installs floating over minor subfloor imperfections using precision click-lock profiles (Unilin or Valinge).

How do you ensure zero batch-to-batch color variation and dimensional stability?

We utilize automated gravimetric dosing systems that control raw material ratios within 0.1% accuracy across all 8 extrusion lines. Print films are sourced from master-roll batches with spectrophotometer color matching under D65 standard lighting. Furthermore, extruded SPC sheets pass through a 4-stage annealing and tempering chamber at controlled temperatures (80°C to 15°C) to relieve internal thermal stress, keeping dimensional expansion below 0.08% under EN 434 testing.

What are your typical order lead times and container dispatch schedules?

For standard decor films and stock thicknesses (4mm, 5mm SPC with 0.3mm wear layer), our lead time is 7 to 15 days from deposit confirmation. Custom print decors, specialized OEM cartons, or non-standard plank sizes generally require 20 to 25 days. Located in Shuyang, Jiangsu Province, our factory enjoys direct highway logistics access to both Lianyungang Port and Shanghai Port, enabling prompt container gate-in and vessel loading.

Do you supply matching accessories and acoustic underlayment options?

Yes. We offer factory pre-attached underlayment options including 1.0mm, 1.5mm, or 2.0mm IXPE (Irradiated Cross-linked Polyethylene) foam or EVA backing, which enhance impact sound insulation (Delta IIC ratings) and underfoot comfort. Additionally, we manufacture color-matched vinyl stair nosings, T-moldings, Reducers, End-caps, and quarter rounds for seamless architectural finishing.

What warranty coverage do you provide for wholesale commercial orders?

Our residential SPC vinyl plank collections come with a 25-year structural and wear warranty. Heavy commercial grade planks featuring a 0.5mm (20mil) wear layer paired with double UV ceramic coating carry a 10-to-15-year commercial warranty. Warranties guarantee zero core delamination, click-joint integrity, and resistance against topical water damage under normal indoor usage parameters.

Can we combine SPC vinyl flooring and PP hollow plastic formwork in a single container?

Absolutely. As a multi-disciplinary manufacturing enterprise, Greenstar allows consolidated container shipments featuring both interior decorative flooring (SPC/LVT) and building site construction materials (18mm PP Hollow Formwork). This flexibility enables distributors and multi-category importers to optimize container space, reduce freight costs, and streamline supplier communication.
