For the CES-EX-LNX explosion-proof linear lights, we have considered various application scenarios and cost factors in the design process. Therefore, we have adopted multiple materials to meet the diverse needs of different customers and projects.

Part 1: LNX Series Explosion-Proof Linear Lights – Carbon Steel Material for Housing

(1) Features:
✅ High Strength – Offers excellent mechanical strength and impact resistance.
✅ Cost-Effective – Lower material cost with high cost-performance ratio.
✅ Corrosion Protection Options – Can be coated with conventional protective layers such as hot-dip galvanization and epoxy coatings to enhance corrosion resistance.

(2) Applicable Environments:
��� General industrial environments (without strong acid or alkali corrosion)
��� Machinery plants, warehouses, workshops
��� Locations requiring high strength but with low corrosion resistance demands

(3) Not Suitable for:
❌ High-humidity, high-salt environments (e.g., offshore platforms, coastal areas)
❌ Strong acid and alkali corrosive environments (e.g., chemical plants, refineries)

Part 2: LNX Series Explosion-Proof Lights – 304 Stainless Steel Material for Housing

(1) Features:
✅ Strong Corrosion Resistance – Resistant to general atmospheric corrosion and mild acidic/alkaline environments.
✅ Durable & Aesthetic – Smooth surface, easy to clean, and rust-free.
✅ Suitable for Food & Pharmaceutical Industries – Low contamination risk and resistant to bacterial growth.

(2) Applicable Environments:
� Food processing and pharmaceutical production (clean environments)
� Mildly corrosive environments (general industrial facilities, outdoor settings)
� Locations requiring a high level of aesthetics

(3) Not Suitable for:
❌ Offshore and marine environments (susceptible to chloride-induced corrosion)
❌ Strong acid and strong alkali environments (insufficient corrosion resistance)

Part 3: LNX Series Explosion-Proof Lights – 316/316L Stainless Steel

(1) Features

316 Stainless Steel for Housing

✅ Excellent Corrosion Resistance – Contains 2%-3% molybdenum (Mo), significantly enhancing resistance to chloride-induced corrosion.
✅ High Strength – Outstanding mechanical properties, capable of withstanding harsh environments.
✅ High-Temperature Resistance – Suitable for high-temperature and high-humidity conditions.

316L Stainless Steel for Housing

✅ Low-Carbon Version of 316 – Carbon content ≤ 0.03%, reducing the risk of intergranular corrosion after welding.
✅ Superior Corrosion Resistance – More suitable for highly corrosive environments, including strong acid and alkali conditions.
✅ Ideal for Welded Structures – Maintains excellent corrosion resistance without requiring post-weld heat treatment.

(2) Applicable Environments

316 Stainless Steel

� Offshore oil platforms, coastal areas (resistant to salt spray and seawater corrosion).
� Chemical plants, refineries (resistant to acidic and alkaline corrosion).
� High-temperature, high-humidity industrial environments.

316L Stainless Steel

� Marine equipment, ocean engineering (long-term exposure to salt spray and seawater).
� Chemical industry, acidic and alkaline environments (e.g., chloride-rich conditions, sulfuric acid, phosphoric acid production).
� High-end industrial applications requiring welding (e.g., pipelines, storage tanks, support structures).

(3) Key Differences Between 316 and 316L Stainless Steel

The primary difference lies in carbon content, which affects corrosion resistance, weldability, and mechanical properties. 316L, with its lower carbon content, offers better weldability and higher resistance to intergranular corrosion.

Comparison of 316 and 316L Stainless Steel of CES-EX-LNX Fixtures

This table clearly illustrates the key differences between 316 and 316L stainless steel, helping in selecting the right material based on specific application requirements.

4. Choose 316 OR 316L Housing for LNX Fixtures?

• For welded applications, 316Lis recommended because its lower carbon content prevents intergranular corrosion after welding, enhancing durability.
• For highly corrosive environments(e.g., strong acids, strong alkalis, salt spray), 316L provides superior corrosion resistance.
• For higher mechanical strengthwithout strict welding requirements, 316 is a suitable choice.

� If the lighting fixture is manufactured with welding or used in extreme corrosive environments (such as offshore platforms or chemical plants), 316L is the better option.
� If welding is not required and higher mechanical strength is needed, 316 is sufficiently durable.

Part 4: LNX Series Explosion-Proof Light – GRP Material (Glass Reinforced Plastic)

1. Features:

✅ Exceptional Corrosion Resistance – Suitable for environments with strong acids, strong alkalis, and corrosive gases (e.g., sulfides, chlorides).
✅ Electrical Insulation – Ideal for explosion-proof areas; non-conductive for enhanced safety.
✅ Lightweight – Easy to install, suitable for weight-sensitive applications.

2. Suitable Environments:

� Strong acid and alkali environments (chemical plants, wastewater treatment plants, paper mills).
� Mining and power industries (moist environments, prevents electric shock).
� Flammable and explosive areas (non-conductive, anti-static).

3. Unsuitable Environments:

❌ Applications requiring high mechanical strength (GRP has lower strength and impact resistance compared to metal).
❌ High-temperature environments (prolonged exposure to high temperatures may cause GRP aging).

4. Choosing Between 316L and GRP for Explosion-Proof Lights

316L stainless steel and GRP (Glass Reinforced Plastic) have distinct differences in application, particularly in corrosion resistance, mechanical strength, impact resistance, and electrical insulation.

Application Environment Differentiation

Choose LNX EX Explosion Proof Linear Light with 316L Stainless Steel Housing → Suitable for environments requiring high mechanical strength, salt spray resistance, and high-temperature tolerance, such as offshore platforms, petrochemical plants, and the food & pharmaceutical industries.

Choose LNX EX Explosion Proof Linear Light with GRP Material → Ideal for environments with strong corrosive chemicals and where electrical insulation is required, such as chemical plants, wastewater treatment plants, the power industry, and humid mining environments.

If your primary applications are in the marine, petrochemical, or food industries, 316L Fixtures is recommended. However, if customers focus on extreme chemical corrosion or electrical safety, GRP Fixtures is the better choice.
