Product Description

Outerdoor Easy DIY Outdoor Garden Wooden Stair 1-17 Step Steel Stringer Stair Riser

We specialize in customized hot-dip galvanized steel stair stringer services for the oversea market, empowering customers with the solid strength of a source factory: We own a modern production base equipped with automatic welding production lines and professional hot-dip galvanization workshops, boasting a monthly production capacity of 5000 sets. We can not only efficiently undertake large-batch engineering orders but also flexibly meet small-batch customization needs. With a fast delivery cycle of 7-15 days, we significantly shorten the project timeline.

Our products have prominent core advantages: Adopting hot-dip galvanization technology compliant with ASTM standards, they can pass a salt spray test of over 1000 hours, making them suitable for high-wear environments such as coastal and high-temperature areas in Australia, and providing rust protection with no maintenance needed for more than 5 years. The welding process strictly follows AWS D1.1 specifications, and each batch of products undergoes third-party load testing and non-destructive testing, ensuring impeccable structural strength. We offer customization of size, load capacity, and mounting interfaces according to customer needs, accurately matching the requirements of various scenarios including residential buildings, commercial buildings, and industrial platforms.

The entire process complies with the international Safety Standard and ISO 9001 Quality Management System. We provide integrated services from demand communication → free design and drawing → production quality inspection → local compliant delivery → installation guidance, eliminating intermediate links and offering higher cost-effectiveness through direct supply from the source factory. Having deeply engaged in the Australian market for many years, we are familiar with local construction specifications and climatic characteristics. Our products can be directly put into use without secondary adaptation, making us a worry-free choice for engineering companies and builders.
