BMG-AT41®

Confused about the properties you should look for in Alloy T41 material? Not sure that it is the proper material for your or your customer’s needs? Are you being told that material offered from a new source will meet the exacting powergen end users’ requirements, but not sure of the exact specification they are offering?

Alloy T41’s use in critical applications means that material offered as meeting basic requirements without the extensive testing of such as our BMG-AT41® could be an expensive mistake (see our blog here for more details on this).

Below we provide our comparison between our BMG-AT41® (based on our purchasing specification); the CEGB standard 02596 GDCD std 2 issue 2 & GEC/Alstom 30/227; Tata’s Durehete® 1055 (from Corus specification publication: “Durehete 1055” and mill cert (“Reported”); and the basic 1.7729 standard BS EN 10269:2013 / 1.7729.

If still in doubt, please ask our sales team for advice.

How to tackle global manufacturing competition

Manufacturing is one of the fastest industries to push a country into economic prosperity. India, China and Germany all sit on the timeline of development. India – emerging as a haven for cheap labour and low rental costs. China, a growing powerhouse, feared by mature markets for its knack in poaching whole industries from their reign. And then there’s Germany – the proof of what can happen when you hone, develop and invest in engineering. Through continuous investment 1 Germany has become a green pioneer of manufacturing excellence.

Unfortunately, as the rest of the world has joined in, Britain has withdrawn its position. UK headlines are spattered with skills shortages, decreased budgets and a failure to meet environmental goals. So, with higher labour costs and limited investment in
UK manufacturing, how can your business compete?

Cut off your competitorsWelding

Due to a globalised market, we no longer compete with our neighbours, but with firms from around the world. To minimise competition, aim for an industry that has heightened barriers to entry. Certifications can be harder to gain in developing companies, blocking their entrance. Try the Medical industry, Food processing or Aerospace for more localised competition.

Consider the Marketing Mix

British Engineering sits in a dangerous position currently. The middle of the market. We lack the prestige of Switzerland and Japan in technology, but can’t match prices with countries like Mexico and Korea. This leaves competition on process, place, promotion and people. UK firms must make their products more available, visible and better supported by customer relationships to differentiate themselves.

Combine product Manufacturingand services

It’s no secret that the UK is a service led country, with services estimated close to 80% 2 of th
e British economy. With the explosion of consultative, contracting and project management companies, why not consider a strategic partnership? Offering an end to end service creates trust in the customer, removes bottle necks and disrupts competitors.

As is often the case, the secret to competing on a global level is not fixed on one factor such as price, but in building a unique proposition that sets you apart.

Your Valve Exhibition 2017 Pocketguide

While we all know how important it is to get out of the office and meet prospects face to face, when faced with a heavy work load we can be reactive instead of proactive, leaving business development by the wayside. With exhibitions costing valuable time and money it’s hard to distinguish the most effective, particularly when defending sales pitches from all angles. However, when done correctly, attending events can become a valuable strategy within your sales plan, simultaneously building your brand image and customer base.

Luckily we have created a handy list of the best exhibitions of 2017, to help you navigate around the brightest events this year, along with some pointers for when you attend.

Utility Week

23-24th May Birmingham

Utility week is a Gas, Electricity and Water exhibition located in the heart of Birmingham. With over 3,000 attendees ranging from market leaders such as British Gas to small businesses and Sole traders, this is an event that is mandatory for any business in the Valve industry. Highlights are sales focused seminars such as “Meet the buyers: Q and A with major water and energy users” and of course the price – 100% free to attend!

Utility Week Live

Oil and Gas Industry Conference

14-15th June Aberdeen

Oil and Gas Industry Conference is a UK based event with attendees including government and regulators as well as prospective buyers. With a prestigious level of speeches and focus sessions from market specialists, the event is focused around new market trends and entrees – making it ideal for revisiting your own strategy if the first half of your year has been lacklustre.

Oil and Gas Industry Conference

Pumps & Valves 2017

4-5th October Rotterdam

With Valve World residing in America this year, those looking to go to a product specific exhibit should look no further than Pumps & Valves. Being one of the fastest growing B2B events since its 2015 inception, this is a keen contender if you can plan an overseas business trip. The show’s modern layout is made complete with their easy to use app; highlighting attendees, conference schedules and allowing customers to scan product information, encouraging prospects to remember you for future transactions.

Pumps and Valves 2017

Maximising your experience:

Get inspired – Thought about expanding into new markets but not sure how? Going to a product specific conference such as PCV Expo can be the perfect introduction, allowing you to see first-hand how other businesses have expanded their industry coverage.

Mix it up- exhibitions tend to attract the same customers each year, with many businesses budgeting the repeat stall cost annually. For wider exposure aim to attend new exhibitions each year, or if reattending larger events map a different route around them.

Dont skip the conference – While it can be tempting to avoid industry talks, these meetings provide a great open space for more natural conversation where you aren’t picketing from a stall. Listening to information from respected talkers will also help you to tap in to up to date terminology, making you appear market savvy.

Plan your events strategy – As expected you will get the most out of your conversations if you research beforehand and come prepared. Business cards will get lost among the masses and you may forget who is going to an event unless you keep a mapped list of attendees. Be strategic on who you are going to target and what merchandise you will be bringing to stay memorable.

Last of all have fun! Let us know in the comments which events you won’t be missing this year…

A Greener Broder

Broder Metals Logo

No, not the logo!

Here at Broder Metals Group we are always looking for ways in which we can reduce our carbon footprint and become a ‘greener’ business.  For example, in 2010 we replaced all of our desktop computers and servers with energy efficient models from VeryPC, a local computer equipment supplier (have a look at what they do here: www.very-pc.co.uk). We also moved to a (semi-) paperless order system in 2013, reducing our paper usage by over 70% and saving hundreds of pounds per year on printing costs alone. We now have a target in place to recycle over 95% of all the paper we use, along with reducing the amount of general waste we throw away (although we have never yet had to throw away any cake!).

More recently we have been concentrating on our premises.  The obvious things (double-glazing, draught excluders, etc) are already in place, so we’ve tried to be a bit more imaginative on other ways to improve energy efficiency.

Warm enough for penguins?

The first step was to expand our server room, which straight away improved the air-flow and reduced the need for cooling fans without risking damage to our IT equipment through over-heating.  We also now have the ability to vent the warm air into the main office instead of losing it outside the building, which in cold weather will help maintain a warmer temperature without having the central heating on all day (great for the members of our staff who grew up in barmy Mediterranean climates!).

Next, we turned our attention to the warehouse. The existing lighting was removed and replaced by LED lighting, which will improve the working environment and uses about 60% less energy than the old lamps.  Additionally, we have installed motion detectors in between our racks so that we are not powering lights when there is no-one working nearby. We have also attached sensors of a different kind to the warehouse yard floodlights, with these being sensitive to daylight levels rather than motion.  This means that in the summer months the floodlights won’t be on unnecessarily all night. The final change to the warehouse was the installation of infra-red heating to replace the old, inefficient fan heating units. This not only uses less energy, but will provide a higher quality working environment for our staff.

Up to this point, all the work undertaken had been to reduce our energy usage, but through the company who provided the LED lighting, we were also able to install a 20kW solar power system on our roof. This will provide over 50% of our electricity over the course of a year, with an expecting operating life of at least 20 years. So, next time you visit us for a coffee, make sure it’s on a sunny day!

The Phantom Painter

Offices often have mysterious goings-on, normally in the form of the magic cleaning fairy who empties bins and wipes away the dust (not to mention the blood, sweat and tears) engrained in certain people’s desks. However last week we came across a new phenomenon, when we came into work one morning to find that several office doors are now ‘vibrant’ orange.

refurbished Broder Sheffield office

Now, far be it from me to make accusations of who might be responsible, but there is one person in the office with a well-known love of all things orange:

Steelworks employee

So the question is: with re-painting the office walls next on the maintenance plan, can we find where Mike has hidden the paint brushes in time?!
