¿Qué es una chapa estriada?

A chapa de acero estriada — also spelled placa a cuadros in British English and widely used across the Middle East, Southeast Asia, and Commonwealth countries — is a flat steel sheet with a regular raised pattern embossed onto one side.

Common pattern types include diamante, cinco barrasy lentil (teardrop). The textured surface enhances traction and load grip, making it suitable for walkways, ramps, stair treads, loading platforms, and truck beds.

Most checkered plates are produced by hot rolling, which ensures consistent mechanical strength and wear resistance across the full thickness range.

Tamaños estándar, grosor y peso teórico

Chapas de acero estriadas are typically supplied in standard sizes for convenience in fabrication and transportation. The most commonly supplied checkered plate standard sizes are listed below.

Espesor (mm)	Tamaño estándar (mm)	Peso (kg/m²)	Peso (lb/ft²)
2.5	1000×2000	19.6	4.02
3.0	1250×2500	23.6	4.83
4.0	1500×3000	31.4	6.43
5.0	1500×6000	39.3	8.05
6.0	1220×2440	47.1	9.65
8.0	1500×6000	62.8	12.87
10.0	1500×6000	78.5	16.08
12.0	1500×6000	94.2	19.30

Nota: The above values are theoretical weights calculated based on base plate thickness.
Raised checkered patterns typically add approximately 3–5% to the total weight depending on pattern depth, and actual weight may vary slightly due to manufacturing tolerances.

Types of Checkered Steel Plates (By Material)

The main types of checker plate are classified by material, including mild steel checker plate, carbon steel checker plate, and galvanized checker plate.

1. Chapa estriada de acero dulce

Chapas estriadas de acero dulce (chapas estriadas MS) are the most common and economical option. They are easy to fabricate, weld, and cut—making them suitable for general structural and flooring use. For projects requiring standard carbon steel checkered plates, you can also explore our ASTM A36 chapa de acero a cuadros opciones.

• Grados típicos: Q235, A36, SS400, S235JR
• Acabado superficial: Laminado en caliente, sin revestimiento
• Aplicaciones: Suelos de fábricas, escaleras y plataformas de camiones

2. Chapa estriada de acero al carbono

Chapas estriadas de acero al carbono ofrecen una resistencia y una dureza ligeramente superiores a las del acero dulce. Se utilizan cuando la resistencia al desgaste y la solidez son más importantes.

• Grados comunes: ASTM A283, A572 Gr.50, Q345, S275JR
• Casos prácticos: Suelos para maquinaria pesada, rampas industriales, remolques de transporte

3. Chapa galvanizada

Chapa galvanizada está recubierto con una capa de zinc para resistir la corrosión, ideal para exteriores o condiciones húmedas. Conservan la misma textura antideslizante a la vez que ofrecen una mayor durabilidad y vida útil.

• Tratamiento de la superficie: Galvanizado en caliente o electrogalvanizado
• Aplicaciones comunes: Rampas exteriores, plataformas marinas, zonas húmedas, peldaños de escaleras

Common Checkered Plate Pattern Types

Common chequered plate pattern types include diamond, five-bar, lentil (teardrop), and hexagonal designs,
each offering different levels of slip resistance and visual appearance.

• Placa de acero diamantado (placa de rodadura) - El diseño más popular para suelos industriales y zonas de carga.
• Placa cuadriculada de cinco barras - Un patrón lineal antideslizante ideal para escaleras, pasarelas y suelos de almacenes.
• Lenteja / Patrón de lágrima - Ofrece una superficie más lisa y uniforme adecuada para uso decorativo o ligero en interiores.
• Placa hexagonal / de nido de abeja - Patrón de agarre resistente utilizado para plataformas de equipos y suelos de maquinaria.

Ambos diamante y placas de rodadura de cinco barras están disponibles en acero dulce, acero al carbono y acabados galvanizadosLa selección se basa en la resistencia, la protección contra la corrosión y el coste.

Typical Grades of Checkered Steel Plates

Common checkered steel plate grades vary by application and required strength.

• For general flooring and stair treads, grades such as Q235, ASTM A36, and S235JR are widely used.
• For higher load-bearing or industrial platforms, grades like Q345 and ASTM A572 Gr.50 are preferred.

Recommended Checkered Plate Thickness by Application

Selecting the correct checker plate steel thickness is essential for load capacity, safety, and service life.

Aplicaciones	Recommended Thickness
Stair treads	3.0 – 4.5 mm
Walkways and platforms	4.5 – 6.0 mm
Vehicle floors and ramps	≥ 6.0 mm
Decorative or light-duty panels	2.3 – 3.0 mm

For stair applications, checkered plate thickness for stairs is typically between 3.0 mm and 4.5 mm, depending on step width and expected foot traffic.

PREGUNTAS FRECUENTES

• Q1: What is a checkered steel plate?
  A checkered steel plate is a steel sheet with a raised surface pattern such as diamond or five-bar, designed to improve slip resistance. It is commonly used for stairs, walkways, platforms, and industrial flooring.
• Q2: What are the standard sizes of checkered steel plates?
  Common standard sheet sizes include 4′ × 8′ (1220 × 2440 mm), 5′ × 10′ (1500 × 3000 mm), and 1500 × 6000 mm plates. Custom cutting is widely available depending on project requirements.
• Q3: What thicknesses are available for checker plate?
  Typical thickness ranges from 2.3 mm to 8 mm. The most commonly used thicknesses are 3 mm, 4 mm, 5 mm, and 6 mm.
• Q4: What thickness of checker plate is used for stairs?
  For stair treads and platforms, 3 mm to 6 mm thickness is most common. Heavier-duty industrial stairs may require 6 mm or thicker plates depending on load requirements.
• Q5: What is the weight of 6mm checker plate per square meter?
  A 6 mm carbon steel checker plate weighs approximately 47–50 kg per m², depending on pattern height and base plate thickness tolerance.
• Q6: What is the difference between checkered plate and plain steel plate?
  Checkered plate has a raised patterned surface for slip resistance, while plain steel plate has a smooth surface. Structurally they can be similar in grade, but checker plates are preferred in safety flooring applications.
• Q7: What steel grades are commonly used for checkered plate?
  Common grades include ASTM A36, S235JR, SS400, and equivalent mild carbon steel grades used in structural and general fabrication applications.
• Q8: Is checkered plate suitable for outdoor use?
  Yes. It is widely used outdoors for walkways, loading ramps, and platforms. Galvanized or coated versions are recommended for improved corrosion resistance in humid or marine environments.
• Q9: What is the weight of an 8mm checker plate per m²?
  plate weighs approximately 62.8 kg per square meter (12.87 lb/ft²), based on carbon steel density of 7.85 g/cm³. For a standard 1500×6000mm sheet, total weight is approximately 565 kg. Use our Calculadora de peso de placas de acero for custom dimensions.
