Step 1: Define your venue and usage level

Answer these questions before you compare specifications:

• What kind of room is it? The product is listed for dance rooms. The supplier describes uses that range from children's dance training institutions, family yoga rooms and personal dance rooms to professional dance studios.
• How intense is the use? Training-level rooms and professional studios point to different versions (see below).
• What finish and colours do you need? Colour options and surface finish differ between the versions.
• What are the room dimensions? The published roll size is 20m × 1.8m × 5.0mm, so plan your layout and seams around 1.8m-wide rolls.

Step 2: Compare the two 5.0mm versions

Both versions are 5.0mm thick. They differ in construction:

Model numbers are grouped by their code pattern. Confirm the exact model-to-colour match with the supplier.

Dance 5.0mm (W2**50): for training-level rooms

The supplier describes Dance 5.0 as a cost-effective product for training-level dance rooms. It names children's dance training institutions, family yoga rooms and personal dance rooms as typical venues. Its four colours (dark gray, light gray, blue and pink) give you more design options, such as a brighter colour scheme for a children's studio.

Dance 5.0mm Ⅰ (W1**501): for professional dance studios

The supplier presents this version as a product for professional dance studios. According to the published description, it has:

• a thicker 1.5mm wear layer, which the supplier links to stronger wear resistance and a longer product life
• a matte surface treatment that reduces light glare
• high surface friction to help stop dancers slipping
• a high-density, high-elasticity, high-flexibility foaming process that improves floor elasticity
• a stabilization layer of black polyester mesh plus glass fiber non-woven fabric, which helps prevent bulging, breaking and deformation over long-term use

It only comes in dark gray and light gray. If your design needs pink or blue, this version will not fit.

Step 3: Check the shared features against your needs

The supplier lists these features for Dance Flooring 5.0mm:

• Materials: PVC raw materials and a professional formula, described as suitable for a healthy indoor environment.
• Wear resistance and slip resistance: The surface and the elastic foam structure work together to meet dance room needs.
• Dimensional stability: The glass fiber layer helps prevent the floor from shrinking or deforming.
• Impact absorption: A high-density copolymer foam layer adds landing elasticity and cushioning. The supplier says this helps protect joints such as the ankle and meniscus.
• Cleaning: A surface treatment makes the floor easier to clean and maintain.

These are the supplier's descriptions. No test values (such as friction coefficient, shock absorption or emission data) are published for this product. If your project or local rules require measured performance data, ask for the relevant test reports before you order.

When this recommendation does not apply

• Outdoor or event use: The product is listed for dance rooms. The source materials do not support outdoor, portable or wedding dance floor use.
• Ball sports or multi-sport courts: This guide covers dance rooms only. Choose flooring documented for that sport instead.
• Other thicknesses or colours:
• Compliance-driven tenders: No certifications for this product are included in the confirmed materials. Do not assume any certification applies.

What to confirm before ordering

Ask Shijiazhuang Langning Sporting Goods Technology Co.,Ltd. for:

1. the exact model number for your chosen version and colour
2. pricing, minimum order quantity and lead time for your market (none are stated here)
3. any test reports or certifications that your project or local rules require
4. installation, subfloor and maintenance guidance for your site

Summary

For training-level dance rooms, children's studios and home practice spaces, the Dance 5.0mm (W250) version gives you four colours and a 1.0mm wear layer. For professional dance studios, Dance 5.0mm Ⅰ (W1501) adds a 1.5mm wear layer, a matte surface and a reinforced polyester mesh plus fiberglass stabilization layer, but only in gray tones. Match the version to your venue first, then confirm the commercial and compliance details directly with the supplier.
