Does Wiemann Metalcraft offer “ball-park” pricing?

No.  Ball park prices are not offered because they are almost always inaccurate and often do not take important factors into account which would be caught during the normal estimating process.

Does Wiemann Metalcraft offer "Value Engineering" or can Wiemann Metalcraft offer improvements to specifications, materials, finishes, fabrication processes which would improve the price or schedule of the work?

Yes. The more information we receive during the estimating phase, the more accurate we can be with our proposal. If you indicate up front that your project is extremely budget driven then we will offer VE ideas from the outset in order to make it as affordable as possible. Alternately, if you provide us with a budget number in advance, we can submit for consideration the type of metalwork we can provide for that price.

 What is Wiemann Metalcrafts normal lead time?

Lead time depends on the size and complexity of the project and the backlog of work already underway. We generally quote the time frame expected for completion for any particular project at the time of the proposal. However because approvals are often lengthy and delay commencement for weeks or months, we reserve the right to redefine the project length at the time that all approvals are received. We can turn many projects around in 12 to 16 weeks from approvals however.

How does Wiemann Metalcraft measure for a curved stair railing?

We must physically measure or template your curving stair which generally involves a crew from our shop traveling to the jobsite by air or by truck and working on site for a few days making a steel or aluminum “template” of your stair. We also use state of the art digital measurement systems to help ensure the accuracy of our work and provide more cost effective solutions to our clients.  

Back to Top


Does Wiemann Metalcraft ever ship work for others to install?

Yes. We have excellent discounts with our freight carriers.  We often manufacture products for others to install excepting most stair railings.

What materials and processes are commonly used by Wiemann Metalcraft ?

Our craftsmen commonly works in cast, wrought or hand forged, and fabricated steel, stainless steel, iron, aluminum, copper, brass bronze, and  monel metal. We can weld, machine, water jet cut, laser cut, punch, braze, solder, bend, shear, hand- form, hot forge, anneal, stamp and cast any of these architectural alloys. We often employ rapid prototyping and 3D modeling to create mock ups, seek approvals and create tooling for custom foundry projects.

Back to Top


Does Wiemann Metalcraft offer Design services?

Yes, we can offer design services on an hourly basis  including the preparation of shop drawings and specifications for bidding. Depending on the type and complexity of your project  we also recommend you consult with a local architect who can help coordinate our work with the other trades that may be involved, while addressing building code related issues.

What types of finishes does Wiemann Metalcraft offer?

Wiemann Metalcraft offers all of the traditional and contemporary finishes for ornamental metalwork. For example, we offer traditional finishes of wax and linseed oil on forged iron, patina finishes for ferrous and non-ferrous metals, as well as complex catalyzed paint and primer systems. Be aware that with ornamental metalwork, specialty finishes can sometimes cost as much as the fabrication of a product. If you do not have a finish specification for your work then we can offer one to suit the requirements of the installation.

How can I keep my project within budget?

If you choose to share your budget with us, we will help design and/or value engineer your existing design to stay within your budget.  If we provide you with a fixed price proposal for your work, we will hold that price unless the scope of work changes.

Why is the Wiemann Metalcraft bid more expensive  than some of the other bids we received?

Wiemann Metalcraft never strives to be the low bidder, but we instead prefer to be the best bidder; bringing together the right balance of quality, service and experience to bring real value to our clients.
Unless we are instructed otherwise, Wiemann Metalcraft will always assume a very high level of finish joinery and finish quality on the proposed work. In addition, our professional project managers and detailers, along with our skilled craftsmen  offer a “turn-key”product  that does not leave the customer with surprises at the end of the job or project management responsibilities.  We will decline to bid projects where the details do not meet our standards for joinery or finish.
And concurrently,  when specifications and details are clear, our bids are almost always equal  to  others.  This is the reason you need to provide as much information as possible to each bidder, so you receive a fair and accurate “apples to apples” result.

What is the difference between Wrought Iron, Cast Iron and Steel?

  • Steel, or more specifically, Mild Steel which is also known as A36 Carbon Steel is the most commonly used material in ornamental metalworking today. It is available in hundreds of sizes in bar lengths from 20' to 40' and also available as sheet. It is relatively inexpensive and strong and has been the main material used since commercially available "wrought iron" was discontinued.  It can be heated and forged, tempered, and formed in many ways making it a very versatile material for ornamental applications. It can also be cast at very high temperatures but this is quite costly and not often doen for ornamental applications and small batch sizes. Steel forms the backbone for bridges and cars, buildings, railings, gates and fence. Steel does have to be protected from water and weather however, otherwise it will deteriorate very quickly.

  •  Ornamental Cast Iron is created by heating iron ore to it's melting point and then pouring it into a sand mold which was formed around a carved pattern. When the pattern is removed from the compacted sand mold, it leaves a cavity which is filled by the liquid, molten iron. Cast iron flows hot and stays hot allowing it to travel long distances and fill complex cavities left by a skilled pattern makers hand. Almost anything that can be carved or formed using clay or wax can be duplicated in cast iron. Cast iron lasts! You will find that cast iron is used, unpainted or treated for manhole covers, water and sewer pipelines, storm drain grates and gates, railings and fence of course,  because it is highly corrosion resistant and lasts for generations without any maintanence. If some flexibility is desired, cast iron can be modified to be ductile or malleable. It cannot be forged however.

  •  “Wrought Iron” in contemporary usage usually refers to the process of iron or steel being “wrought” or worked by hand and implies a degree of decoration is involved.  (e.g.  “I  prefer a wrought iron fence” and “ I prefer a decorative steel fence” mean the same thing today)  However, “Wrought Iron”  is also a very specific type of iron alloy which preceeded modern steels and was widely used for ornamental and structural work prior to 1930s,  when modern smelting processes and higher grades of “steel” became available.  Thus “Wrought Iron” because of it's cost to manufacture, was discontinued altogether by 1960 in favor of cheaper steel alloys.  Since true Wrought Iron is no longer made except from recycled content in specialty micro mills, almost all ornamental metal shops use A36 Carbon Steel in their fabrication and forging operations where ironwork is required.  It should be noted here that Wrought Iron is highly corrosion resistant, much like cast iron, it has a grain much like wood, and will outlast steel 10 times or better when unmaintained. The fences made from true Wrought Iron which were installed in the late 1800's around Philadelphia and many other parts of the coutry are still standing as testament to the durability of this alloy.

    See the NOMMA website here:
     http://www.nomma.org/support/wrought/wrought.htm for an excellent article by Todd Daniel which details the technical differences between Wrought Iron and Steel.

What is the difference between Brass and Bronze?

Brass and bronze are both copper based alloys. There are hundreds of different variants on the blend of metals to make these copper based alloys, but, in general, Brass is alloyed with zinc while Bronze is alloyed with tin.  The Copper Development Association is the trade association which is dedicated to, among other things, cataloging the numerical system which identifies copper based alloys - hence the CDA designation before the numbers listed here and elsewhere.

Copper based alloys have different metalurgical compositions which allow them to be fabricated, milled, melted and forged for different and specific industrial and architectural applications. For example; architectural bronze CDA385 is extrudable and somewhat forgeable, but it cannot be rolled into sheets. Meanwhile, the alloy formula for Naval Brass (CDA464) allows it only to be rolled into sheets. Both alloys are very simialr in composition, nearly 40% zinc and 60% copper but they have very different properties even though they are also a good color match. This is why complex bronze doors and railings are often made from a variety of copper based alloys.

We generally use the following alloys in our work and often times we use more than one copper alloy within each bronze fabrication:  Silicon Bronze (Cast and wrought) CDA 876 and CDA655, Muntz metal (sheets) CDA280,  Naval Brass (sheets CDA464 and some bars), Free Maching Bronze (bars and shapes for fabrication)CDA360, Commercial Bronze (sheets) CDA220 and Architectural Bronze (bars and extruded shapes) CDA385.  You can find a wealth of detailed information about these metals at the Copper Development Association Website www.copper.org

Does Wiemann Metalcraft ever work with Laser Cutting, Water Jet Cutting, or CNC Milling of metals?

Yes.  Because of our 3D CAD capabilities we can work with any applicable CNC machining processes to economize and/or accelerate production schedules. We also use 3D modeling and rapid prototyping or SLA processes to generate samples, models and patterns for foundry.

Back to Top


What are the CAD capabilities of Wiemann Metalcraft?

Wiemann Metalcraft uses AutoCAD, Solidworks 3D and Autodesk Inventor 3D modeling software.  These files can be plotted in 2D and in some cases on a 3D SLA or sent electronically for revisions, comments and field coordination.  In addition, we use digital photographs extensively to aid in progress billing, design and project coordination.

Can Wiemann Metalcraft send me samples or mock-ups for review or approval?

Yes, for a charge.  We often create a full size sample for review and approval prior to beginning work.

How does Wiemann Metalcraft warrant its work?

Wiemann Metalcraft stands firmly behind all of its work. We are bound by law to hold a one year standard workmans warranty on any of our products anywhere in the country. But we are not satisfied until our customers are delighted with both our services and our products. In this way we are able to work for the same clients year after year.

I have an existing exterior iron railing which is rusting, what is the best way to maintain it?

We recommend that if the railing is badly deteriorated or loose in any way to find a qualified local ornamental iron or welding service shop to make necessary structural repairs. If the railing is in sound shape then remove the rust and failing paint with a wire brush or sand paper, naval jelly and or chemical paint remover. Then use a rust inhibitive primer or a zinc rich primer and a good quality rust inhibitive top coat. All should be available at your local hardware store. Be sure to follow the paint manufactures recommendation for coating thickness and dry times. A thin coat of paint will not weather as well as a heavier coating and a coating which is too heavy will not cure properly.

Exercise care when removing old paint as it may contain lead. By sandblasting or abrading the paint by mechanical means, you will create a dust plume which contains lead which can be tracked to adjacent building or inhaled. For this reason, when working with lead based paints please use paint stripper so the paint remains can be disposed of properly.

Does Wiemann Metalcraft offer design services for Gated Communities and Gated Entries for Communities?

Wiemann Metalcraft designs gate, and electronic entry system and fencing, wiring requirements, or other site furnishings we may be fabricating,but generally  we defer overall landscape, site and urban design and planning of the entry to a qualified architect or  landscape architect. 
Be aware that set backs, city and state building codes, hydrant access, emergency vehicle access and many other considerations will come into play with a gated entry and the best person to manage this is a qualified design professional familiar with local zoning and building code requirements.

Back to Top



What is the best gate operating system for my residence, my gated community or subdivision?

Wiemann Metalcraft has installed over 100  gates and gate operators and entry systems over the past 10  years and can provide the specifications and designs  best-suited for your gated entry as part of our scope of work.

 Why does custom ornamental metalwork cost so much?

The single greatest cost of our goods sold is labor. This is a true story today as it was 100 years ago for our trade. Therefore, the more labor there is involved in the work the more expensive the work will be. Additionally, we rarely enjoy the benefits of production processes due to the fact that we are making something new or different every day. If General Motors or Ford had to make your car one at a time, to your specifications for size, design, color, metal, ect.. then you can be assured it would cost much much more.
