How do I stop my Colorbond gate from sagging?

Date: 28-11-2024


You have just installed a brand new gate, and you feel pretty chuffed about its stunning Woodland Grey shade. It matches your Colorbond fence perfectly, and you cannot wait to show it off to your mates.

Soon the gate starts creating a swinging problem, and it has sagged to one side. Every time you open it, the dreaded creaking sound invites that questionable look from your partner. The gate is creaky and lopsided and you get this sinking feeling that you've made the wrong choice.

You invested in a good quality Colorbond gate with the expectation that it would be top-notch in style and performance. However, your saggy gate has become the talk of the street.

But the real issue here is not the quality of your gate; the problem is either poor installation or lack of maintenance, or potentially there are issues with the gate post installation.

This is where Pinus Sawmills, the most trusted fencing and gate suppliers in the Canberra region, can ensure that your provided gate is installed right the first time. If your gate creates issues like sagging or creaking or you keep getting side-eye from your neighbours, then keep reading!  

Can genuine Colorbond steel gates sag? 


Colorbond is high quality steel with a pre-painted weather resistant finish. When you choose Colorbond, you pay for a robust and durable quality gate made according to Australian standards and designed to withstand the Australian climate. Despite the quality of the material, sagging can be a problem in some applications.

Poor Installation

Your fence gate cannot stand strong for years if the posts are not deep enough in the ground, or if there has been an improper installation where the hinges were not attached securely. Sometimes a lack of alignment or poor levelling can also be the reason for a saggy gate. Installation involves many aspects and if you miss any, even the most expensive gate can sag.

Weak or Loose Hinges

You might have invested in a top quality gate in a trendy shade like Evening Haze or Pale Eucalypt. However, any attempt to save money on hinges will cost you in the long run. Your driveway gate will start to droop when the hinges do not support the weight of the gate. Those poor quality hinges will wear out soon and then the problem of sagging will become inevitable.

Weak Frame Support

Your gate needs a solid frame to stay in place for long. If the gate frame is weak and cannot handle weight, then bending or sagging is obvious. The problem of a weak frame becomes more evident with repeated opening and closing of sliding gates.

Ground Shifting

You put your money to good use by choosing a gate from the product page of Colorbond. Their robust quality gates certainly withstand the harsh Australian climate. However, you cannot prevent the issue of ground shifting caused by heavy rains or drought. This situation can create issues with the alignment of gateposts, resulting in strained hinges or a sagging gate.


Wear and Tear


Constant use and exposure to the weather can take their toll on your gate. Even the strongest gates and fence panels need regular maintenance to stop sagging. You can also invest in protective post caps to prevent damage from water and other elements. 

How to Prevent Future Sagging Issues


Some homeowners might think a weekend DIY project for installing a double gate is doable. Sadly your effort to save some cash is usually where things go sideways.

A wobbly gate often originates from not setting up the posts right. Hiring an expert means everything will be straight, sturdy, and balanced from the get-go. This way, your gate stays strong, and you will not have to worry about it drooping after a few weeks. 

You should avoid taking the DIY route and call the Colorbond product specialists from Pinus Sawmills, who can provide you with a comprehensive and cost-effective quote.


Use Heavy-Duty Hinges

Sometimes, little things can lead to a gate giving up on you. Do not cut corners and go with sturdy hinges. Frustration can soon kick in if you have installed your sturdy gate on weak hinges. Invest in high quality hinges that can handle the weight of the gate and the existing fence.


Secure Gate Posts


Bury the gate posts at least 900mm deep and set them in concrete. The extra effort you put in the beginning is totally worth it. Strong gate posts give your pedestrian gate a solid foundation. So start with a sturdy base and gate stile material to avoid alignment issues.


Choose the Correct Gate Size


Surfmist, Night Sky, Deep Ocean and Manor Red are all the most beautiful Colorbond Colours. But while deciding on what vibrant colour best suits your environment, don't forget to pay attention to the size and weight of the product. Heavier gates can sag more easily, so go for a standard gate design that keeps things sturdy but not too heavy.


How to fix a sagging Colorbond gate


Panicking is acceptable if you did not pay attention to the above aspects and now your gate fittings have started sagging. Thankfully, it is fixable and you can do it the following way:


Tighten Loose Hinges


The first and obvious problem with a sagging gate is loose hinges. So check these and use a wrench to tighten them. This step is enough to fix a slight sag, but more issues will require another solution listed below.


Add a Brace


Uneven weight distribution can be a reason for a sagging gate. Use a steel or metal brace to fix the problem by installing a diagonal brace at the top corner of the gate opposite the saggy bottom.


Replace Worn Hinges


A quick and easy way to stop a gate from sagging is to replace the problematic hinges with some heavy-duty ones to support the weight of the gate. 


Adjust the Channel Post


Dig around that wobbly gatepost and give it a good push back into place. Pack the soil tightly when the gatepost is tall and straight.

Next you will need some concrete to lock it in. It will prevent the problem of a shifting gate post which can be the reason for sagging. 

The good news is that a sagging gate is not a permanent problem. There is no need to feel frustrated, especially when you have invested in a top-notch product by Colorbond.

Your gate will keep enhancing your curb appeal for years. Just make sure you go with quality materials, the right installation and regular maintenance. A few small steps are enough to keep your Colorbond gate standing strong.
