    Main Structural Components

    Steel Stair Stringers
    Plate Steel Treads
    Handrails & Guardrails
    Steel Stair Stringers

    The stair stringer is the primary load-bearing component of the staircase. We can provide different structural configurations, including:

    • I Beam Stringer
    • H Beam Stringer
    • C Channel Stringer
    • Box Section Stringer
    • Fabricated Plate Girder
    • Customized Steel Beam

    The appropriate beam type is selected according to stair span, live load, stair width, architectural requirements, and available installation space.

    Plate Steel Treads

    Steel plate treads provide a durable walking surface and can be manufactured with different surface configurations according to application requirements.

    Available options include:

    • Plain steel plate
    • Serrated anti-slip plate
    • Checkered steel plate
    • Perforated steel plate
    • Grating tread
    • Customized anti-slip tread

    For outdoor applications, anti-slip surfaces are recommended where rain, oil, dust, or other contaminants may affect pedestrian safety.

    Handrails & Guardrails

    Steel handrails and guardrails provide additional safety for users. They can be fabricated from round steel tube, square tube, rectangular tube, or other steel profiles according to the project design.

    Features

    1.High Capacity Load-Bearing

    The combination of structural steel beams and steel plate treads in essence allows for a solid industrial/commercial access system.

    2.Steel Construction Strong

    If steel products are engineered and coated properly, they have exceptional strength and durability.

    3.Anti-Slip Options are Available

    Spiral stairs can be fitted with serrated plate treads, checkered plates, perforated plates or bar steel to enhance grip.

    4.Versatile Beam Selection

    A number of different beam/stringer arrangements are available to suit the span, load, look and installation method.

    5.Tailored Dimensions

    The width of the stairs, the full height of the stairway, the number of stairs, the depth of each step, the height of the riser, the height of the handrail, and the beam configuration are all customizable.

    6.For Outdoor Use

    For outdoor and industrial applications, hot-dip galvanizing, protective painting or other types of corrosion protection systems may be used.

    Products Show

    Customization: Steel stairs can be customized with a variety of finishes, such as powder coating, galvanization, or paint, allowing for endless design possibilities. They can also be combined with other materials, such as glass or wood, to create a unique and dynamic look.

    Safety: Steel stairs can be equipped with safety features such as handrails, non-slip treads, and illuminated step edges to enhance user safety and accessibility.

    When considering steel stairs for a construction project, it's important to work with a qualified professional to ensure that the design and installation meet building codes and safety standards.

    Packaging & Shipping

    When packaging steel stairs for shipping or transportation, it's important to ensure that the materials are adequately protected to prevent damage during transit. Here are some general guidelines for packaging steel stairs:

    Secure the Components: Disassemble the steel stairs, if possible, to package individual components for easier handling and reduced risk of damage. Secure individual stair treads, handrails, balusters, and other components to prevent movement or shifting during transit.

    Use Protective Materials: Wrap individual components in protective materials such as bubble wrap, foam padding, or corrugated cardboard to safeguard against scratches, dents, or other surface damage. Consider using edge protectors to minimize impact damage during handling.

    Secure Packaging: Place the wrapped components in sturdy, appropriately sized boxes or crates. Use cushioning materials such as packing peanuts, foam inserts, or air cushions to fill any voids and provide additional protection against impact.

    Labeling and Handling Instructions: Clearly label each package with handling instructions, including directional arrows for orientation, weight information, and any special handling requirements. Indicate the fragility of the contents, if applicable, to ensure proper care during transport.

    Consider Waterproofing: If the steel stairs will be exposed to outdoor elements during transportation, consider using waterproof materials or enclosures to protect against moisture damage.
