Sure-Step® Step Iron

As a result of using a combination of galvanised steel and superior engineering polymers, Sure-Step® is the result of the development through 2001 to meet the future market and standards.
The Leader in Corrosive Resistant Step Irons for Stormwater and Sewer Manholes

Sales of steps commenced in 1994 by ISL’s predecessor company. The technology of these plastic encapsulated products was based entirely on galvanised steel. In 1998 the company developed a galvanised steel and polypropylene composite product which provided improved corrosion resistance, but would not meet the higher BS EN 13101:2002 and AS1657:2018 standard required of step irons today. As a result using a combination of high strength galvanised steel and superior engineering polymers, Sure-Step® is the result of the development through 2010 to meet the future market and standards for sewer step irons.
The benefits of Sure-Step plastic encapsulated step irons

- Correct selection of high performance materials provides Sure-Step® with superior loading properties.
- Greater resistance to corrosion than conventional sewer and stormwater step irons.
- All components are manufactured in Australia thereby providing security of supply.
- The design incorporates a non slip tread and resistance to side slippage.
- No painting or other protective coating required.
- Plastic encapsulated step irons can ultimately be recycled.
- Comprehensive Product Range.

An Alternative to Steel

The design of the Sure-Step® plastic encapsulated step iron enables it to meet stringent performance standards. All the components are manufactured in an Australian quality controlled manufacturing facility.
The Sure-Step® step iron is approved by a number of prominent Water Authorities globally, including the MRWA, to meet their special performance requirements for use in sewerage applications in Melbourne.
Raw materials used in the production of Sure-Step® stepirons are sourced only from leading global suppliers who comply with international standards.
The injection moulding process used to manufacture the product components is computer controlled to exacting tolerances.
Industrial Steps & Ladders is a Quality Assured Supplier. The quality manual and procedures are audited annually and certified by Bureau Veritas Australia to AS/NZS ISO 9001: 2015

Design & Manufacturing

Sure-Step® step iron has been designed for the following applications
- factory fit pre-cast concrete
- fitted or fixed into cast in situ concrete manholes onsite during construction
- fitted into pre-cast manholes and secured at the construction site into ferrules cast into the manholes
Sure-Step® step iron is manufactured using an engineering polymer with a continuous central galvanised steel support for the full length of the step iron.
The fully plastic encapsulated Sure-Step® step iron side arm and rung section is 26mm (nominal) square.
The 70mm embedment length is delineated by a change to a ribbed and rounded profile being 26mm (nominal) diameter. The embedment length is required to meet the pull-out resistance load required in EN13101:2002 and AS1657-2018.
Each side arm has a 20 mm high raised section at the rung end to prevent side slippage. The rung has a grooved non – slip pattern moulded into the tread to limit frontal and rear slippage.
The Sure-Step® stepiron is marked with the trade name and the relevant standard and date of manufacture on the rung.
The Sure-Step® stepiron polymer overlay component is manufactured using a computer controlled injection moulding process.
As the overlay process is semi-automatic every Sure-Step® stepiron is inspected for quality conformance at the manufacturing and packing stage of the process.
The Sure-Step stepiron has been designed to be used in stormwater, sewerage and other general access applications. The design of the Sure-Step® stepiron was optimised to offer a high quality corrosive resistant product at a competitive price
Plastics – Materials for the Future

Plastics are one of the most resource efficient and versatile materials available to society and make a significant contribution to achieving the goals of sustainable development.
Products made from plastics provide an affordable alternative to traditional materials and give the community access to a higher standard of living. ISL has harnessed this versatile material to deliver a new, lighter range of corrosive resistant ADD-A-STEP ladders alongside our Sure-Step® stepiron range.
Importantly the plastics industry helps to save resources, fossil fuel and energy. Plastic products also save water and preserve food.
Plastics only consume a small fraction of the world’s oil as feedstock – just 4%.
Plastics are too valuable to waste after serving a useful life. Plastics can either be recycled or used as an alternative fuel.
Plastic waste has a calorific value at least equal to coal and with lower CO2 emissions.
