R&S Grating COVID-19 Update – 25.03.20

In these uncertain and rapidly evolving times, we wanted to send a message of support to our customers and keep you informed of the impacts on our operations and the precautions we’re taking to keep our staff, customers and supply-partners safe. We are monitoring the situation closely and all decisions are based on the latest available advice from the authorities. While we remain open for all sales, pick ups and deliveries, we have made some changes to our operations in the interests of everyone’s safety.


We have taken the decision to close our show room in an effort to minimise face to face contact between our staff and the public. While our front door is locked, our sales team remain ready on the phones to take all enquiries. Pick ups may now proceed directly to the despatch office (down the left driveway of the property, as signed), which is now permanently attended, to pick up pre-ordered items. If you arrive without having placed your order, or need to modify your order, you can call us on (03) 9238 5888 at any time and one of sales team will facilitate your order or modifications for immediate pick up at the despatch office.


To minimise contact between our delivery staff and the public, we are now offering contact free delivery. Our drivers will unload your order by crane or hand and place it where instructed. In lieu of signing a delivery docket, the driver will ask for the receiver’s full name and take a photo of the position where the goods were left. If you would like a copy of this photo/receiver’s name, please contact our office.We ask that anyone receiving a delivery from us maintain a minimum distance of 1.5m from our staff and turn away when coughing or sneezing. All our drivers are carrying antibacterial hand sanitiser should anyone wish to use some.


Our sales team are postponing site and office visits with our customers, except where strictly required and requested by our customers. As always, our Sales Manager Steve Skinner can be reached by mobile phone or by calling our office and likewise for our Area Sales Rep. Neil Ward.


For our office staff and production team, we have made some changes to minimise their risks of contracting Coronavirus. We have made hand sanitiser and N95 masks available to all staff. We have staggered our production hours so that morning, lunch and afternoon tea breaks are staggered between groups to minimise the concentration of staff in the tea room and comply with the government’s four square metre social distancing requirements. We have provided our staff with the government’s advice on best hygiene practices and minimising the risk of contracting Coronavirus. All staff have been instructed not to attend work should they feel ill, or become aware of contact between themselves and a confirmed COVID-19 case.


As the situation continues to develop we will continue to adapt our response and operations in the best interests of our staff’s health and safety and that of the wider community. We remain committed to offering our customer’s the best possible service, without compromising on anyone’s safety. We understand these are trying times and would like to thank our customers for their understanding.

Water Flow Test of Weaved Grate

Full Scale Hydraulic Inlet Testing of a Weaved Grate

At R&S Grating, we’re no strangers to extreme testing, whether it’s throwing a fully loaded B-Double at a grate at 100km/h or putting a weaved grate through one million load repetitions, we take great pride in the quality of our product range and relish the opportunity to test them to the harshest conditions that the Australian environment can throw at it.


In our latest test, the University of South Australia conducted a full-scale hydraulic inlet test on one of our signature products, the weaved grate. The 17m x 3.2m Roadway Surface Drainage test rig, the only of its kind in the Southern Hemisphere, was constructed in 1991 at the University of Adelaide and allows for longitudinal slopes between 0% – 16% and cross-fall slopes between 0% – 5%. With an adjustable approach flow between 0 – 400 l/s, the test rig features a capture and bypass pond to measure the collected water at varying slopes and approach flow rates. The rig was fitted with two R&S Grating weaved grates, measuring 1900x600mm and 1900x900mm respectively, with an additional inlet of 1900x450mm being measured by the use of plates covering part of the grates.. Weaved grates are a high strength product that offer between 65-75% open surface area, while still easily achieving the bicycle tyre penetration resistance (BTPR) requirements of AS3996.

Both a standard grated inlet pit and combined side entry and grated pit inlet configuration were tested. All tests were conducted with a cross-fall slope of 3%, to simulate typical road conditions, with the longitudinal slope and approach flow rate being varied. The longitudinal slope was varied between 0.25% and 8% and was a fixed variable for each test. The approach flow rate was varied between 0 l/s and 400 l/s, with the contents of both the capture pond and bypass pond being measured.

With the grates fitted, the longitudinal slope was set for each test and the approach flow was gradually increased. The large variety of configurations and clear opening inlet sizes offered great insight into the hydraulic capacity of the weaved grate.

With larger inlets, and the lowest longitudinal slope of 0.25%, the grate captured 100% of the water supplied, up to a 180 l/s approach flow rate. As the approach flow rate continued to increase, the grate continued to capture staggering quantities of water. At the full approach rate capacity of 400 l/s, the weaved grate captured 340 l/s, or 85% of the water supplied.


At the other end of the longitudinal slope rate spectrum, with an 8% decline, the weaved grate captured 100% of the water supplied, up to an approach flow rate of 80 l/s. At the rig’s approach flow rate capacity, 400 l/s, the grate captured 265 l/s, or 66% of the water supplied. The full results for all longitudinal slopes featuring three 1000x800mm grates are given in Figure 3.

For the smallest inlet size tested, 1000x450mm, the grate captured 100% of the approach flow water up to 85 l/s with the smallest longitudinal slope of 0.25%. For the largest slope, 8%, the grate captured 100% of the supplied water up to 38 l/s. The full results of the smallest inlet size are given in Figure 4.

The impressive test rig conducted a total of 48 tests of varying inlet sizes, kerb profiles and longitudinal slope inclinations, providing superb data on the hydraulic capacity of weaved grates for almost any situation imaginable. The schematic of the test rig is shown in Figure 5.

The hydraulic capacity testing of the weaved grate adds yet another tick to the impressive range of tests that the weaved grate has been subjected to and passed. Designed and manufactured at R&S Grating’s Dandenong South factory, the versatility of the weaved grate allows it to be manufactured to load ratings from class C through to class G of the Australian Standard AS3996.


The load-bearing capacity of the weaved grate has been extensively tested with both static, repetitive loads and also dynamic, high-impact loads. Now used extensively throughout Melbourne’s network of arterials and freeways, the weaved grate has stood the test of time in every application.

Small Gap, Big Difference!

We had a bit of an Abbey Road moment capturing these photos, but the scenario perfectly highlights the benefits of heelguard (small gap) grates!


We recently manufactured and supplied 600mm clear opening heelguard trench for a busy intersection in Cecil Street, South Melbourne.  The roundabout forms a junction between residential properties, community parks and local pubs and cafes, making it a thoroughfare for all manner of pedestrians at all hours of the day and night.  Complicating the design was a history of damage from garbage trucks and buses.


Heelguard grates were the ideal solution, ensuring the area could be safely accessed by pedestrians, bikes, wheelchairs and even those wearing high heel shoes.


Our very own Abbey Road moment on Cecil St, South Melbourne.

R&S Grating designed a system of grating that not only provided a small gap of around 5mm, but was also class D (heavy duty) to ensure that when buses and trucks mounted the kerb there were no issues.


To ensure that the aesthetics of the popular intersection were maintained, R&S Grating meticulously rolled and welded curved bars to match the curvature of the intersection.


The heelguard bars were meticulously cut, tacked and welded to match the curvature of the intersection.

The result was four trench runs on all corners of the intersection that now allow sufficient drainage to the trenches while ensuring public safety and simultaneously providing a strong solution if large vehicles mount the kerbing.

Yes, we’re changing!

You might have heard about some of our changes already. R&S Grating spent a great deal of time in 2012 and 2013 redeveloping our range of grates and covers to improve on the already tried and tested design.

One of most exciting developments has been the introduction of hinges and bolt down methods in many products across our range, as a standard inclusion.  To learn more about what products we're changing, and how, have a look at our "We're Changing" booklets.
